Steps to Reproduce Behavior

Use the following steps in Visual FoxPro 5.0. You can also do the process in Visual FoxPro 3.0b in order to appreciate the changed behavior in Visual FoxPro 5.0.

1. Create a form in the visual desktop using the Form Designer. On the form place the following controls:

   a. a label

           name = 'Label1'
           caption = any text
      b. a textbox
           name = 'Textbox1'
           controlsource = thisform.mytext
           ToolTipText = any wording for that property's caption
      c. a timer control
           Interval = 1000
           Timer-event method containing the following:
   
              ThisForm.Label1.Caption = TIME()
   
      d. a command button
           Click method that issues the command
   
              ThisForm.Release
   
   

2. Add a custom property named "MyText" (without the quotation marks) to the form.

3. Set the ShowTips property of the form to True (.T.).

4. Run the form. Position the cursor over textbox1. Observe the ToolTip.

5. In the Visual FoxPro 5.0 form, change the interval of the timer to 5000.

6. Run the form again. Position the cursor over textbox1. When the ToolTip is cleared move the mouse very slightly.
