When you drag the favicons on the bookmark toolbar and click with the right button, mozilla is blocked and it's impossible to do anything, mozilla block every signal to x, you have to kill it.
I've run into this a few times now in Linux. I'm usually just installing Mozilla and dragging a new home page to the home button. If I drag over the bookmark menu, the menu pops up. My guess from the behavior is that the menu takes focus, but the bookmark doesn't vanish or stick with the mouse as it should. I was able to windowshade the browser, call up a term and kill it, but only by clicking A LOT on the title bar. Until I shaded the browser, I wasn't able to launch a term. First time this happened to me I did a ctrl-alt-bksp to kill X because nothing else worked.
Reporter, please always say which version you use. Is your problem the one described in bug 143031? pi
Yes, it think it look like to be the same one.It was with rc1 and rc2 is not affected. I've forgot to post a comment after my test, sorry.
