DAX corruption

Hi all,

This issue is not specific to 3.1.8 but it seems to remain.  I have a Flex-6600.

My poor computer has had a fair number of SmartSDR versions installed including Alpha Test versions.  I've removed all but 3.1.8 and restarted to ensure the system is fairly fresh.  System is a Windows 10 machine on the latest OS version with all updates installed.

I've been doing some work on FRLogger with respect to better support of FT8 and FT4.

I have noticed that after some period of time WSJT-X simply stops decoding.  My time is NTP'ed and pretty much spot on.   The signals in the wide graph look good.  Dax level looks good, there are signals on SmartSDR and the slice is set to the correct DAX channel but decoding just stops.

I have taken baby steps to resolve the issue:

1) I have turned the DAX channel off then back on - No improvement
2) I have changed slice Dax channel to none then back to 1 - No improvement
3) I have terminated WSJT-X and restarted it - No improvement

The only thing that seems to solve the problem is to terminate DAX using the DAX control panel and restart it.   Of course to do this I have to terminate WSJT-X and restart it.

I have a friend across town that I sold my 6500 to a while back and he pretty much leaves WSJT-X up and decoding on 4 slices 24/7.   I will ask about his OS and other specifics but the simple fact is that he does not end up with corrupted DAX.

The strange thing for me is that there is no obvious indication that DAX has gone south.  The wide graph looks fine, the Dax levels look fine but nothing decodes.

I seem to remember there were other threads about similar issues but I could not find them.  I'm wondering if someone has experienced the same issues and if there are any known fixes.

    This problem has plagued Smart SDR on all versions. The only quick fix is to shut the DAX Control panel then manually restart it as already mentioned.

    I have found running Web Browsers and Youtube videos makes the problem worse.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
