top panel gone completely...and i cant get the logout options by pressing on the desktop for a few secs (used to be avialable previously)....another thing that happens is the side panel keeps getting displayed and disappearing in quick succession...until i hold the panel in place by pressing the screen when it stops...not sure whats going on? no, i dont have any themes or anything undesirable cosmetics such like but do have lxde, ica receiver etc.
