I can still reproduce the issue by doing the following:

 

1. Open 2 browsers with http://cutesoft.net/asp/multiple.asp

 

2. From the first window, select the first texteditor's value and paste it into the second window's first texteditor.

 

3. From the first window, select the second texteditor's value and paste it into the second window's second texteditor.

 

4. Repeat steps 2 and 3 until one of the windows locks up.

 

Please note that I could not reproduce this issue in FireFox. Only Internet Explorer (versions 7 and 8).

 

Thanks in advance for any help you can provide.
