BUG: Mouse Down Triggered on a Minimized Window

• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0a

SYMPTOMS

The MouseDown event of a form occurs when the user presses a mouse button when the form has the focus. It is very useful when trying to detect mouse clicks or performing a specific action when the mouse is pressed. Forms created in Visual FoxPro running under Windows 3.1, Windows for Workgroups, and Windows 95 execute code in their MouseDown events when the Form is minimized. This behavior is not expected because MouseDown events should occur only when the Form is active.

WORKAROUND

Place the following code in the MouseDown event of the form:

   IF THISFORM.WindowState <> 1
      FORM::MouseDown
      * Any event, such as wait window prevents the default MouseDown event
   ENDIF

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Steps to Reproduce Problem

4. Minimize the form.

5. Click the minimize icon with the right or left mouse button. The MouseDown event occurs.
