I've been using XD for a while now to do design work for the website of the organisation I work for. I use it on a work laptop - Surface Book 3 and a home desktop - Custom-built gaming spec PC. I have no issues using the program itself, but what I am finding, on the work laptop, is that if I go idle - comfort break, go to make a hot drink, when I return and log back in XD will have closed. Its not a huge problem because I don't lose any progress with the cloud saving. But the behaviour does seem odd.
I don't have administrator access on the machine. But checking the windows event logs nothing is reported. Also, no other applications close in this scenario, just XD seems to be affected.
My best guess is that its related to the laptop's idle behaviour. As its a work machine, when its idle it becomes locked, and I must enter my password again to then continue. Its always in this scenario that I resume working to find XD no longer open.
Using XD on my home desktop, I don't experience this issue. This machine doesn't lock, if I leave it idle.
