I was in a rush to finish something at work in the last couple of days and while I usually don't mind it that much, as I was quickly moving the mouse across the code and frantically writing new code, Eclipse was showing so many tooltip it was driving me nuts! I spent a couple of days googling every now and then for a solution with no joy... Apparently there's lots of suggestions out there on how to disable tooltips altogether, increase the tooltip timeout and even some suggesting a relation between menus delay and tooltip delay. Finally, my pain was brought to an end when I decided to look for "hover" (the term used in Eclipse) in TweakUI settings and it was right there under my nose!
A peek using RegMon reveals that the setting goes into HKEY_CURRENT_USER\Control Panel\Mouse\MouseHoverTime (REG_SZ) registry key. Now at 300 (note the value is in milliseconds), with my sanity restored I'll get back to work now! I believe the same key applies to Windows Vista.
