On Users/Groups/Machines/Profiles/Platforms Remove panels in JCT,
using the mouse to select a particular item to remove would fail
intermittently, i.e. either selected a wrong item or could not
select any.

System config: x86 server, Solaris 2.6, GeminiPlus H13.

To reproduce the problem:
- startJSD and startJCT.
- click on Profiles/Add and add 50 Profiles.
- click on Profiles/Remove.
- click on Profile Name window to bring up the list of profiles.
- the first several times to select an item to remove would work fine.
  The problem would often occur if either select the item on the top
  or bottom of the list to remove. After that the mouse clicks on one
  item, but either the selected item might be another or the item
  could not be selected (i.e. the Remove button is still faded).
- For example, click on profile20 on the list, but the Profile Name
  window shows another one, e.g. profile24.
