  • Microsoft QuickBasic 4.5 for MS-DOS

This article was previously published under Q39193


It has been reported that several QuickBasic Version 4.50 programs (including DEMO1.EXE) fail to run on a Tandy 3000. One customer has a built-in EGA card connected to a RGB CM11 monitor. This customer has tried this program on several other 3000s, all with EGA monitors. The same program works on the customer's 3000 if it is compiled with QuickBasic Version 4.00. There were no TSR's running on the customer's system, and the mode co80 and co40 DOS commands had already been tried.

Microsoft has confirmed this to be a problem in Version 4.50. We are researching this problem and wil post new information as it becomes available.
