UCCNC remote session crash

Hi, I'm using UCCNC 1.2109 on Win10 with AXBB-E. Bug scenario is as follows:

- Log into windows user account locally and run UCCNC
- Start a gcode program
- Log into same user session from a remote computer on the network using Remote Desktop (ie to check machining progress)
- UCCNC crashes

Note: UCCNC works perfectly fine in a remote desktop session if instantiated from one - it's only switching between local and remote sessions that causes the crash.


Windows event log:

Not a direct solution to your scenario with regards to Win10 remote desktop, but I use TightVNC to get a remote view of my UCCNC controlled machines without any issues.
