When I use different screen dimensions, Dos works fine with it.  How are you changing the screen size?  The referance which dos uses as the screen dimensions are the bytes in the BIOS area:  0040:004A is a word containing the screen width in columns.  The word at 0040:008A contains the screen length -1 (thus 24 means 25 lines).  Also, some earlier versions of dos may not use these. If so you're out of luck.
