I have installed Ubuntu 11.04 (Win7 Dual-boot) today, so I am a newbie in the world of Ubuntu. I like it, because it is very new and interesting to me, but there is a thing, that really annoys me. When I have a window open, it is usually okay to use the mouse, but if I open a new window (like firefox) then I can't use the mouse on the 2nd window.
I can't click on anything, but I can use the keyboard to navigate with the arrows, but it is really hard to me, because i can't use 2 windows at one time. Please reply as soon as possible.
