When using QB.EXE from QuickBASIC version 4.50 on an IBM PS/2 Model 25
or 30 with an MCGA, the mouse cursor position is not tracked
correctly. This does not happen if the machine has a color graphics
card.
For example, if you pull down the File menu in the QuickBASIC 4.50
editor, hold down the mouse button and drag the cursor down the menu,
you will see that the highlight bar indicating the current menu
selection does not keep up with the movement of the mouse cursor.
Also, the farther the mouse cursor is moved down the screen, the wider
the disparity becomes.
The same problem exists in the QBX.EXE environment supplied with
Microsoft BASIC Professional Development System (PDS) version 7.00.
This problem does not occur in versions of QuickBASIC earlier than
4.50.
Microsoft has confirmed this to be a problem in the QB.EXE environment
that comes with QuickBASIC version 4.50 and in the QBX.EXE environment
that comes with Microsoft BASIC PDS version 7.00 (buglist7.00). We are
researching this problem and will post new information here as it
becomes available.
