I get this and have had a few other reports.
open a new Excel, lock the screen (win + L) then log back in (assuming your screensaver is pw protected), no change to Excel.
Open the VBAIDE then close it and lock and unlock – now a zombie IDE appears with no toolbars or menus.
This was always caused by crappy COM addins, but just recently I have seen it on totally clean machines, and it happens in safe mode too. Only noticed it on dual screen set ups so far And its Excel 2007 SP1.
Anyone else seen this?
Anyone know what causes it? and/or fixes?
Is it fixed in SP2?
