JFormDesigner issue with javax.swing.JArrowButton

[Max]

Hi,

I'm designing Swing GUI in JFormDesigner v.5.0 RC 2. I have
seaglasslookandfeel-0.1.7.3.jar and jdk1.6.0_26.
When changing Look and Feel to Sea Glass, the JFormDesigner pops-up a
message saying "Failed to load llok and feel related class
javax.swing.JArrowButton. This may happen if a beacn uses its pwn UI
delegates". After the look and feel change, radio buttons and
checkboxes have black box instead on icon in the designer and in run-
time.

Regards,
Max.
