Thanks Jos for the interesting "in-depth" analysis, I just need the program ran in vDos which is more convenient than DosBox. Minh

After longer testing I would like to add, that the problem caused the specifics of my DOS programs, associated with an unusual number of memory allocations, and a special vDos compilation from Jos helped. Minh

Thanks Jos for your valuable and fast help, a problem with the popup window also resolved. Thanks again for your time. Minh

I know i know, but this program consists of many files, I will try to pack the lightest version... Thanks for attention to you both, Minh

This is a non-commercial program for own use. Interesting that it's running in XP as DosBox as well, but can not run in vDos. As I said, the message is shown only in Windows 10 when I did not use Task Manager. In Windows 7 it just hung without any message (and then I stoped by TM). Minh

Hello Jos, I have some a DOS program that was running well in DosBox, but not in vDos. Running under Windows 7 it's just hanged (I had to use "manager stop"), and Windows 10 displayed a message "vDos exception: Stack overflow". What causes this error? Thanks for your possible answer, Minh
