FULL PRODUCT VERSION :
1.6.0_01
also 1.4.2_14

ADDITIONAL OS VERSION INFORMATION :
Windows XP pro SP2

EXTRA RELEVANT SYSTEM CONFIGURATION :
using Windows XP desktop theme

A DESCRIPTION OF THE PROBLEM :
JCombobBox paints an extra space to the left of the button which hides the end of the selection in the editor. The problem occurs when a larger font is used to cause the component to be higher that the default font. It also happens if a size is set using setPreferredSize or setSize which is taller regardless of the font.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Occurs with or without a layout manager on a panel.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should see the entire selection and be able to type up to the arrow.
ACTUAL -
See all but the last bit, and typing stops short of the arrow.

This bug can be reproduced always.
