SYMPTOMS
========

When you use the _ED* editor functions to achieve cut, copy, and paste
functionality in an application and the editor functions are part of a toolbar,
use of the commands will cause Visual FoxPro to quit abnormally.

STATUS
======

Microsoft is researching this behavior and will post new information here in the
Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Behavior
---------------------------

1. Create a new form, and place a single text box on it.

2. Enter some text into the Caption property of the text box.

3. Copy and paste the code listed in the "Sample Code" section into a .prg file,
  and then run the program.

4. Run the form.

5. Highlight the text in the text box, and choose Copy from the toolbar.

6. Delete the text from the text box, and choose the Paste from the toolbar.
  Visual FoxPro will quit.
