I have a very weird problem which I've been never experienced.
Now, all the menus and right-click of the mouse is disabled. I am not saying that I cannot see the menu. There are menu! However, it doesn't react whatever way now. Therefore, go to 'Tools --> something --> something' is not applicable for me at all. Morever, right-clicking of my mouse does not show anything. I don't know the reason. I turn on my laptop and read a book for several minutes, browse IBM website, and I found that my mouse doesn't react for the right click. So, I tried to check something from menu (I didn't know what must I do, just habitually i tried to access menu), but menu didn't work too.
Please let me know how to fix this.
SUSE Linux 11.4 (32bit)
Firefox (I even cannot check the version!!! because the Help menu isn't working)
