I have added a choice to a frame. Run the attached application. Click on Choice. Drop-down will be shown. Press the left mouse button on one of the items, drag the mouse to a different item and press & release the middle/right mouse button. The drop-down will disappear. Now choice will retain the previous selection. Now click on the choice again. Drop-down will appear. Now you would see one of the items being highlighted and one of the other items will have the focus. The selected item shown in the choice component will change automatically to what was selected last time.

This is confusing and at no point in time 2 items in the drop-down can be highlighted. This is reproducible only on XToolkit and not reproducible on Motif, Win32. This is reproducible on Mustang-Beta as well as RC. I reproduced it on SolSparc10-JDS with Mustang-b65.

Use the attached sample test to reproduce the bug.
