The logging program (Logger32 v3.50.356) that I use is linked to SmartSDR through COM4 port. Since using the latest versions of SmartSDR and Logger32, this COM port link crashes when trying to re-assign the slice that is associated with the COM port. Logger32 closes the COM port and SmartSDR CAT gives the following error message:
"SmartSDR CAT (v2.2.8.190): An unhandled error has occurred: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserver exception was rethrown by the finalizer thread.
Inner Exception: Object reference not set to an instance of an object.
[details of the exception]"
Whilst Logger32 closes the COM port I don't know whether or not that is because of it being removed by the slice re-assignment process failing in SmartSDR CAT. In other words which application is driving the fault condition.
I've been using SmartSDR/CAT/DAX/Logger32/Flex 6700 together for about 2 years without this issue occurring. The PC's running on Win 10 v1803. Any ideas as to whether this is a CAT or Logger32 issue, or just down to me doing something wrong!

Mike,
Thanks for your suggestion. COM port assignments look OK to me. Used KJ3P's batch script to check, see
However ......
The problem seems to have gone away. Maybe I should have re-booted Win 10 to check if that cleared the problem, as I can re-assign COM4, which links SSDR with L32.
Re-boot, re-boot and re-boot - maybe I will remember next time!

I have not had this issue recently, as when I have operated I have used the Flex/Maestro combination away from the PC, so not had any COM port integration with Logger32 (L32). However, I have been doing some general admin in the shack this morning so had SSDR and L32 running in the background on the PC and noticed that the COM port issue, reported in my initial post, is still occuring. Re-booting the PC does seem to clear it for a few changes of slice, but as the error seems to occur randomly this may be unrelated.
I have tried Ian's suggestion of setting up a dedicated COM port for L32 - I chose COM8 - but straight away the same thing occurred. L32 dropped COM8 and showed the error message below right, followed by SSDR posting the error message below left.
I don't know if it is related to SmartSDR CAT v2.2.8 but my setup only started to show this problem since the most recent upgrade

Update
Installed SSDR v2.3.7 today and opened N1MM Logger + to try out the "spots" feature (which works great!). I then found that the same thing happens with N1MM that occured with Logger32, discussed above. To summarise: when I edit the COM port, which communicates the frequency of the selected slice to N1MM, the 'Client COM' is dropped and an error message appears from the N1MM application.
So with N1MM Logger + and Logger32 both behaving in the same way when trying to change slice on the COM port is there something that I have not got set correctly with SmartSDR CAT (which is not on v2.3.7).

What you have done is ungracefully ripped the spots comport out from under the running application. This is why you are getting an error message from N1MM.
You have to shut down the spot communication socket in the application before changing the port number.

I don't understand, Tim. I wasn't trying to change the port number but the slice character associated with COM9.

Sorry, I misread your first paragraph since you said you edited the Com port (Actually it is a network UDP port) and didn't include that you were changing the slice designation, I assumed you were changing the UPD port number.
I have entered this into our bug tracker as issue #6447. Thanks for the bug report.

Eric and Tim,
Here's some detail of the exception for #6447. This was done yesterday and today, although the issue with Logger32 occured with the previous version of SmartSDR (N1MM+ was untested on that version)
and clicking Save one gets the following error message from N1MM+
Moments later an error message from Flex
Double clicked on COM8 to change slice association from slice A to B - it worked (this time!)
The ‘Client COM assignment didn’t disappear, and I was able to change slice to B
and save it. Logger32 of course then shows the frequency associated with Slice B.
Then the error messages from Logger32
and from SSDR

Issue as related to N1MM Logger +
CAT9 assigned to N1MM+ (v1.0.7208.0)Double clicked on it to change slice association from slice A to B
A second or so after opening the ‘Client COM’ drop down went blank
Editing the ‘VFO A Slice’ to Band clicking Save one gets the following error message from N1MM+
Moments later an error message from Flex
Issue as related to Logger32
COM8 assigned to Logger32 (v30.50.357)Double clicked on COM8 to change slice association from slice A to B - it worked (this time!)
The ‘Client COM assignment didn’t disappear, and I was able to change slice to B
and save it. Logger32 of course then shows the frequency associated with Slice B.
I would say that the issue occurs with Logger32 roughly 80% of the time. The consistent way to avoid the issue is to close the port (in Logger32), re-assign the COM port and then open the port.
Below is an example of SSDR/Logger32 COM port dropping out during edit:
First the ‘Client COM’ is droppedThen the error messages from Logger32
and from SSDR
