Is SSDR v2.1.33 for Windows releasing memory correctly?

I have noticed when starting SSDR from cold, the associated memory usage is approximately 230MB. If that instance is disconnected by another user on the LAN, the usage drops slightly as would be expected. However, when reconnecting the on the first computer again, the memory usage slowly increases from the previous level and eventually settles to a around 30M more than a freshly started instance of SSDR. Each subsequent cycle of disconnect/reconnect 'ratchets' the memory usage up by this rough figure of 30M. Clearly, if this goes on unchecked there will eventually be a memory resource problem.

I see this behaviour on three machines; one Win 7-64 bit,4G. One Win 10-64bit,16G and one Win 7-32 bit, 2G. It doesn't seem to be machine specific. The only way to get SSDR to release the (hogged?) memory is to close it and reconnect to the radio from cold.

Has this been noticed already? Could it be a bug? If this is by design, what is the purpose of retaining an ever increasing amount of memory?

Many thanks. Paul
