I have a permanently viewable panel along the bottom edge of my screen that is fine, however my hover-over panel at the top edge sometimes decides to move itself.
Sporadically it can appear across the middle of my desktop, sometimes opening up there, or hastily moving itself back to where it belongs, at the top. If the panel doesn't move itself I have to manually move it again to the top.
The position across my desktop changes also, thus far I can't see a pattern or anything that is causing this and it appears to occur randomly to me.
There appears to be no problem with the panel disappearing once the cursor is moved.
Any info or help much appreciated.
