	Problem appears to occur any time an editable widget is given focus in the property sheet,
	then some other object is selected in the workbench so that the contents of the property
	sheet changes.

This bug is claimed to be fixed in 204 build. Needs verification.

Comment 4 Joe Szurszewski CLA 2001-10-17 12:36:16 EDT 
This problem is still present, reproduceable as originally documented.
Comment 5 Joe Szurszewski CLA 2001-10-17 13:52:06 EDT 
Re-opening.
Comment 6 Randy Giffen CLA 2001-10-17 14:05:27 EDT 
I could not reproduce this in 204
Here is what I tried

1. Created the following class
public class Loop {
	public static void main(String[] args) {
		boolean t = true;
		while(t) {
			System.out.println("asd");
		}
	}
}
2. Set a breakpoint on the println
3. Ran (Debug) the class
4. When stopped I selected the breakpoint and in the property sheet set enabled
to false (leaving the cell editor active).
5. Pressed resume
Comment 7 Darin Wright CLA 2001-10-17 15:06:47 EDT 
Perhaps this is because we are using a different version of the workbench
from the ZRH team stream.
Comment 8 Darin Wright CLA 2001-10-19 16:21:39 EDT 
When I use the 205 workbench code, I have no problem.
Comment 9 Darin Wright CLA 2001-10-19 16:22:32 EDT 
Verified.
