Vdos freeze after a while

[cyberjc]

Hi, I recently installed Vdos on windows 10 and my legacy application ran perfectly. However, if I minimize it, after a while not using it, the Vdos is stuck in the task bar, I cannot Maximize nor Close, I should kill the application (but in the same time I can re open another instance ...) I don't know how can I fix this problem.  Thanks for your suggestions

The only thing that comes to mind is that your PC is joined to a domain, or your program is accessing networked files. Every three hours of continuous use, the register nag will popup and vDos will only honor a mouse click on that…

I can confirm this.
If the nag appears while the application is minimized, it's not possible to click on the nag. I found no solution but to use Task Manager to terminate vDos.

It does not appear to be possible to minimize or un-minimize while the nag is in place.
