I'm stuck at work atm but, abit more info on the start menu might help someone find my problem.
I stylehacked most of the start menu from an different theme i liked, then altered a few colours/gfx.
The 2 transparent lines only happen on extended start menu item (wmc in screenie) and then dissapear when it retracts or goto all programs etc.
Perhaps i'll have to start that bit from scratch to get it how i want, i only modded someone elses to my tastes to save time.
Was just hoping someone else had the same problem in the past and knew how to fix it to save time.
thx 3am for the status pane lines, it was only 1 light grey pixel that caused it (now transparent)
