can't click on buttons in firefox 4

[Robin]

Binary package hint: firefox

When trying to click on 'submit' type buttons, or images acting as buttons on web forms: the mouse pointer doesn't change into a hand, and I can't click on the button, either the entire surface of it, or only a part (top part, bottom part, or a corner, depending on webpages).

It also affects text boxes (such as the one I'm currently typing into: I can't click inside the text area starting from the 2/3 to right end).

I'm having similar problems with Firefox 4 under Ubuntu 11.04.

Nearly every second button/link/text box can't be clicked/used and sometimes buttons/links/boxes can only be clicked/used in some parts of the button, box or underlined text. Sometimes it help to scroll down and up again on the same site, sometimes I have to reload the page (and, finally, very often I have to use Opera, which works perfectly under 11.04).

During the last days I I got the feeling that the problem is not limited to firefox 4. I noticed that sometimes ubuntu doesn't react directly when I'm using the mouse or touchpad. Sometimes I have to repeat two or three times, what I wanted to do (e.g. move a Window with the Mouse).

And now I found out that Im not the only one who has these problems. Look here:

(and eventually here: https://bugs.launchpad.net/ubuntu/+source/light-themes/+bug/741112)

A workaround might be to "autoremove xserver-xorg-video-nouveau", see page 3 of the above mentioned thread:

I didn't try this out, because I'd like to wait for removal of the bug instead. Hopefully it will be there very soon, because this bug is extremely annoying.
