I've been running Linux Mint 7 XFCE on a DELL Latitude C610 for sometime with no problems.
Today I am getting some odd windows management issues:
[1.] Open windows don't show in the task bar.
[2.] Unable to resize windows.
[3.] Icons for maximizing the window size, minimizing the window size or closing the window are no longer visible.
[4.] Unable to scroll through open windows using ALT / TAB.
Any ideas on what is going on and what can be done to resolve would be appreciated.
