Start11 ver 1.2 new bug
I updated to 1.2. Behavior not previously seen in taskbar autohide is when taskbar appears (bumping cursor to bottom of screen), entire taskbar is shifted about one-third to the right. Clock and tray are presumably off-screen, and in any event not visible. Rebumping cursor causes the taskbar to redraw in its proper position to the entire width of the screen.
It's not "reproducible" per se (unknown what triggers it), but it happens with regularity. It's perhaps once an hour or so.
