SUMMARY
Programs running interpreted Basic may fail when using screen mode 9 when the Microsoft Mouse driver is loaded.

This information applies to Microsoft Basic Interpreter versions 3.2 and earlier supplied with MS-DOS and all versions of the Microsoft Mouse driver.



MORE INFORMATION
When using an interpreted Basic such as GWBasic or BASICA, programs that use the following line may fail if the Microsoft Mouse driver is loaded: 10 SCREEN 9 This statement puts the video adapter into an EGA mode. The mouse driver may get confused about what video mode is actually being used after this call, causing a hang or other problems with the program.

To work around the problem, use the most current version of the Basic Interpreter.
