STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the sample code provided in Windows XP, using the Windows XP windowing style.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No white strip to the left of the drop down arrow.
ACTUAL -
There is a white strip to the left of the drop down arrow.

REPRODUCIBILITY :
This bug can be reproduced always.
