Roman, thanks for the ping. Just downloaded and built classpath cvs 2005.12.19
- I hadn't tested since 2005.11.21.

I confirm that the PR24651 and PR24651b testcases work fine on my system. 

Also, the nested popup-menu on my imageviewer test app (niffler) can be
shown, has the correct size, and lets me select menu items.
However, menu redrawing is incredibly slow. Switching between the nested 
submenus takes literally a second (handstopped) on my Athlon 2600+; I 
consider this as unuseable. The problem becomes more pronounced when the
underlying image is big (e.g. a 2300x1700+ digicam image). Possibly the
huge delays are due to JViewport/JScrollPane/Image repainting issues
(it seems that the repainting repaints the whole image, and not just the
area covered by the (sub)menu), but I can only reproduce the bug with
JPopup/JMenu. 

Roman, could you please retest with niffler.jar and confirm that switching 
between the submenus on the popup 'feels' very slow? If so, please close 
this bug and add a new nsted-menu-redrawing-very-slow bug and add me to the
cc: list.
