Check and uncheck the checkbox within an applet and sometimes it stays at check state and
won't toggle for a number of times. To reset, you just need to click enough
times to change the state. The Problem exists with JRE 5.0 Upd 14 and not with upd 11.
A check box which is not inside of an applet doesn't appear to exhibit the problem.
The customer has given us access to a test case. In order to reproduce the problem, please see the information in the comments section of this report.
I'm attaching a screen shot of the applet with the checkbox that is exhibiting problems.
