Minimizing RDCMan immediately causes Unknown diconnection reason 3336

For a long time I've been using the older version of RDCMan which got discontinued, with no issues. Now that RDCMan is a live again, finally downloaded the latest v2.92. Thank you for bringing it back!!

However, I'm having a serious issue with it. No matter what server I connect to, if I minimize RDCMan, it immediately disconnects me from my servers, and when I restore the window (even if it is a second later) I see the message:

Disconnected from xxxxxxxxxxxxxx
[Unknown disconnection reason 3336]

I tried rebooting, and tried connecting to other servers and the issue persists.

I tried using Windows' mstsc.exe Remote Desktop Connection client and have no issues at all with minimizing for any period of time. The connection is maintained, so the issue is specific to RDCMan, and not RDP itself.

    Had the same issue. Changed my display settings in RDP properties from reconnect with new resolution to No Scaling and then it worked fine. Hope this helps.
