The information in this article applies to:
- Standard and Professional Editions of Microsoft Visual Basic for
Windows, version 2.0
- Microsoft Visual Basic programming system for Windows, version 1.0
- Microsoft Windows version 3.0
SYMPTOMS
In Windows version 3.0, the mouse behaves unexpectedly in both Visual
Basic version 1.0 and 2.0 under the following conditions:
- A Visual Basic program is run from the environment (VB.EXE) or from
an executable using the run-time module.
- The program has a form that contains menus.
- While holding a menu open with the left button, if you click the
right mouse button, the mouse selection appears to be inactivated.
- Moving up or down the menu while holding the left button down,
causes no selection until you get several inches below the pop-up
(or pull-down) menu. At that point, the mouse causes selection
again from the remote position.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article when used with Microsoft Windows version
3.0. This bug was corrected in Microsoft Windows version 3.1.
MORE INFORMATION
This problem occurs when running a Visual Basic program that has
menus. It requires a mouse with two buttons and has been reported with
both the Microsoft and the Logitech mouse.
Steps to Reproduce Problem
- Run the Cardfile program that comes with Visual Basic. You'll find it
in the Samples subdirectory.
- Put the mouse cursor on one of the menu labels and press the left
mouse button to activate it.
- While continuing to hold down the left button, move the cursor to a
menu item within the pop-up menu to highlight the menu item.
- While holding the left button down, click the right button once.
The menu item should no longer be highlighted.
- Move the mouse from the item you were selecting. Observe that the
mouse no longer activates submenus, and the menu does not retract.
- Continue to move the mouse down from the menu. At some point, the
highlighting of the submenu items will be activated again.
- Upon stopping on a submenu item and releasing the left button, that
menu command will execute.
NOTE: This behavior also occurs if you open a menu and, while holding
down the left button, you use the right button to click the screen.
