FULL PRODUCT VERSION :
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195] Service Pack 2

ADDITIONAL OPERATING SYSTEMS :
Microsoft Windows XP [Version 5.1.2600]


A DESCRIPTION OF THE PROBLEM :
If you set the Windows Look And Feel, the tooltips
associated with JButtons will intercept mouse clicks
intended for the button. The button does not fire an
action event and consequently no action occurs.

Frequently, the tooltip appears just as the user is
clicking the button and so there is no visual cue that the
user must move the mouse to not click on the tooltip.

If you do not set the Windows Look And Feel, it is
possible to click on a tool tip that is partially
convering a button and the button still fires.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Launch the test code.
2. Hover the mouse cursor over the button until the
tooltip appears.
3. Click on the button directly (avoid clicking on the
tooltip) and note the "click" string appears on the
console output.
4. Repeat steps 2 and 3 but this time, click on part of
the tooltip that is in front of the button. Note that
there is no new console output.
5. Remove the line that calls UIManager.SetLookAndFeel and
recompile. Now when you click on part of the tooltip that
is in front of the button, the button fires.

EXPECTED VERSUS ACTUAL BEHAVIOR :
The tooltip should not consume the mouse click regardless
of which LookAndFeel is installed.

REPRODUCIBILITY :
This bug can be reproduced often.
