i removed the window transparency and just used the window mask and resolved
my problem cause the transparency is not so important for my application.
thanks, bruno

If you're using X11 or windows, the transparency code depends on a
component placed on top of all other components to trigger window
repaints whenever anything below it is repainted. On repaint, the
top component paints the frame contents into a buffer, and then
composites that buffer onto the screen, preserving the buffer's
transparency.
You may need additional repaint triggers, or your system may have
trouble keeping up with the screen compositing (even when writing
native code, microsoft recommends keeping frames with alpha blending
small, since they can't take advantage of DirectDraw rendering (this
may be different under Vista).
What is your platform (OS, hardware, VM version, etc)?

Hello, my name is Bruno and i´m a Java Developer from Brazil.
I use de clockDemo code (found on the jna.dev.java.net page) to
build a GUI with a Transparent Window and a JInternalFrame. I added
some components inside that frame and the JButton its disappearing
some thimes, some times it blinks a while. When i turn off the
window transparency activated by the WindowUtils method the problem
dont occur.
can you give me some help?
