MORE INFORMATION

Steps to Reproduce Behavior

1. Start a new Windows CE project in Visual Basic 5.0. Form1 is created by default.

2. Add two CommandButtons to Form1 (Command1 and Command2 by default).

3. Double-click Command1 to create a Command1_Click event procedure.

4. On the form, double-click Command2 to create a Command2_Click event procedure.

5. In the Command2_Click event procedure, add the line of code "hello" without the quotes.

6. Press the F5 key to run the project.

7. Close the project (in the run-time environment).

8. Add a letter, such as "x", to the end of "hello."

9. Press CTRL+Z to undo the operation; the previously added character should be deleted.

10. If you press CTRL+Z again, the entire Command1_Click procedure may be deleted.

11. If you press CTRL+Z again, the Command1_Click procedure may return.

    NOTE: Continuing to press CTRL+Z may cause other procedures to be deleted and then returned.
