FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :
4NT 3.02B Windows NT 5.00

A DESCRIPTION OF THE PROBLEM :
When switching between internal frames, using the right
mosue button and poping up a menu at the same time, focus
is not going to the popup menu.

This causes focus problems when using the arrow keys. Focus
is going to the invoker control, not the menu.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile and run the attached code
2. Right click on the second tree to get the popup menu
3. Press the down-arrow key.

EXPECTED VERSUS ACTUAL BEHAVIOR :
Actual:
The nodes on the tree view are getting selected.

Expected:
The items in the popup menu should be getting selected.

REPRODUCIBILITY :
This bug can be reproduced always.
