I installed lxde desktop after my clean installation of Kubuntu lucid. I like the option of having both a fast or feature filled desktop available for use. And when I run KDE I still use lxterminal and pcman as my default apps. However, ever since I installed lxde desktop the above two apps have not worked properly.

Usually, when using a lxde component I can do one or two mouse clicks and the cursor freezes -- some times I still can move around by using the keyboard (but it becomes unreliable).

Any idea what could be causing these mouse problems?
