Last night I tried running compiz using compiz --replace but it hasnt had the effect Id hoped for. The windows now all appear small in the top left corner and cant be resized, dragged and dont have any of the buttons (close, minimise etc.)

Also on firefox the drop down menus (such as file) cant be access because when the cursor hover on them they close. Also, desktop items are now half hidden under the top panel.

How can I find out whether compiz is the window manager or xfce is?
Should I just restore to before I ran compiz? If so, how?
If I installed compiz config manager would I be able to solve this?

Any help is appreciated
