The QuickBasic environment can be invoked with the /H option, which enables the highest line mode supported by the video card. If QB.EXE is invoked with the /H option from MS-DOS while in 25-line mode, and a normal exit from the environment is performed (by pressing ALT+F X), then the video mode is reset to 25-line mode upon returning to MS-DOS.
If an exit is performed using the Run menu's Make EXE And Exit command, the video mode is properly reset to 25-line mode during the compilation and LINKing process, but upon completion, the video mode is reset to 43-line mode.
Microsoft has confirmed this to be a bug with QuickBasic Versions 4.00, 4.00b, and 4.50, and with the QB.EXE included with Microsoft Basic Compiler Versions 6.00 and 6.00b (buglist6.00, buglist6.00b). This problem was corrected in Microsoft Basic Professional Development System (PDS) Version 7.00 (fixlist7.00).
