Normal for DOS apps. > fixme:int31:INT_Int31Handler lock selector not supported Locking memory was only necessary in real DOS because paging out critical interrupt handlers and such under DOS was a recipe for disaster.

Then again, if your app is a DPMI app, perhaps something does not handle this right once the app enters protected mode. (You could ask the last developer that I remember working on DPMI, Jukka Heinonen, I doubt I'll have much time to fix a not-so-minor problem like this myself.) _______________________________________________ wine-users mailing list wine-users@winehq.com http://www.winehq.com/mailman/listinfo/wine-users
