Tested with merlin_beta-refresh b73 on Windows 2000 and Whistler beta (japanese).

Clicking the checkbox or button with image file on JCheckBox or JRadiubutton component,
the following error is thrown;

To reproduce;
1. Extract attaced file(test.tar) and compile.
2. Launch program.
   % java JRadioButton
       or JCheckBoxTest
3. Comes up dialog.
4. Click the banana or broccoli image.

Then, you can see the problem.
However, this messages are dispalyed only once every buttun with image.
So, clicking the same buttuon twice, this messages are not displayed anymore.

This problem does not occur on merlin-beta-refresh b72.

And this problem is not seen in windows NT or 98 japanese with b73.
