The latest upgrade of the Avast! anti-virus (I got upgraded today) has a new feature called "sandboxing" or some such.
It is set up to decide all by itself if a programme is "suspicious" and then does something or other - no idea what really.
But the effect on both games is as follows:
- In full screen mode, after a key press or two, the game terminates with no warning, straight to the desktop.
- In Windowed mode, at least a red border is drawn round the game window to let you know it does not like it.. Again, after a key press or two, it exits to the desktop without warning.
So I finally found this new "feature" in the file system tree, and set it to "ask" mode, in order to see what it's beef was. The default is "auto" or something like that, which seems to be "terminate programme".
Everything then worked perfectly, and there was no longer a red border round the game window in Windowed mode! .
This "sand box" mode is a seriously weird "feature" IMHO, I'll probably turn it off like I did another new feature which "rates" the website you are visiting with a confidence bar thingy.
Anyway - if you get game termination and have just have just had your Avast! anti-virus update, you know what to do now.
Cheers
