MORE INFORMATION

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.

Create a form in the visual desktop using the Form Designer. On the form place the following controls:
1. a label
  name = 'Label1'
  caption = any text
2. a textbox
  name = 'Textbox1'
  controlsource = thisform.mytext
  ToolTipText = any wording for that property's caption
3. a timer control
  Interval = 1000
  Timer-event method containing the following:
```
           ThisForm.Label1.Caption = TIME() 
```
4. a command button
  Click method that issues the command
```
           ThisForm.Release 
```

Add a custom property named MyText to the form.

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

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

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

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

The ToolTip on the Visual FoxPro 3.0b form persists as long as the cursor is over textbox1. The ToolTip on the Visual FoxPro 5.0 form clears when the timer fires. With the 1000ms interval it can never be restored. With the 5000ms interval moving the cursor with the slightest MouseMove event restores the ToolTip.
