When a popup dialog opens while a menu is being displayed, the interface freezes completly - while the mouse can be moved and the application continue to run and draw things, no more input is accepted from either mouse or keyboard. at this point the only thing left to do is to kill the Xserver using CTRL-ALT-BKSPC (I haven't tried to kill kwin from a terminal - that might work as well).

I've seen this a few times w/o being able to reproduce it consistantly, and most times I can still get away from a lock using ESC or something.
But I found out how to reproduce the freeze consistantly on my system using the KWalletManager:

- have kwalletmanager running
- make sure all the active wallets are closed
- type a URL for a site that has a login form and for which kwallet has a password stored. a good example is a webmail interface.
- before the site loads, open a menu or a bookmark menu from the bookmark toolbar.
- once the kwalletmanager popsup the password dialog for the default wallet, kwin freezes completly.

This seems related to Bug 45403, though I wasn't able to reproduce that specific bug - the cookiejar alert lives in happy co-existance with menus - it does not even close them as the comments in that bug state.

I'm thinking that the same fix that was done in kcookiejar to solve Bug 45403 might need be done for kwalletmanager.

I'm using XFree 4.3.99 (4.4 pre-release) on a NVidia card but using the opensource driver. I have menu shadows enabled but not transparency.
