I have been using DOSBox version 0.74 under Windows XP for years now. I typically have many windows open at once and quite often, one is a DOSBox window. It works fine.

I have now set up DOSBox on my two Windows 7 systems. It does not work so well on them. When my Command Prompt window has been over the DOSBox window (not the console window) and then the DOSBox window gets the focus again, the display goes funny. It does not happen every time, but it does happen frequently. When it goes funny, the only part of the window that updates properly is that part of the window that was covered by the Command Prompt window. The rest of the DOSBox window does not update.

This has nothing to do with the fact that I use WordStar. DOSBox could be sitting at its command prompt, and this display oddity will occur.

I have never had this problem under Windows XP. All three systems are all using the same config file text.

The config file that I use is close to bog-standard. The only difference between it and the distributed config file is the startup [autoexec] section. I mount some drives and set some environment variables.

Any ideas? What further information would you need?

Sincerely,

Gene Wirchenko
