Please describe the problem:
The setup assistant window was so wide that is wasn't possible to click the forward button. First i had to move the window so far to the left until the button became visible at the right border of the screen. 
After finishing the assistant this trouble is still the same with the other windows within evolution. If a window is wider than the screen than it's not possible minimize it by mouse and it has no effect to click the full screen button  either. Screen setting is 1024 x 768 but it makes no difference to switch to
800 x 600 p.e.. Other programs (firefox, open office p.e.) are working properly. 

Steps to reproduce:
Just start evolution. If the first window isn't out of size from the beginning, than play around a little bit with the size of the window or open some other windows within evolution. It will happen soon...


Actual results:
The window will be out of size (screen) sooner or later. Most times sooner...

Expected results:
That you can resize windows as you want to...

Does this happen every time?
Sure, most times sooner...

This trouble isn't really a new discovery. It seems like it's a long term case or well known bug. :-O
