Tooltip delay in Windows

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.


  1. Dan, thanks for posting; I'd never heard of TweakUI but installed it after reading your post and now got rid of these annoying super fast hover tooltips in eclipse, thanks!

  2. Hi Willem,

    Glad to hear someone else found this useful too :-) TweakUI is a great tool, wish Microsoft would write a similar one for Vista, maybe in time, who knows.

    This thing was driving me crazy in Eclipse as well, so I'm glad I found your post! Thanks alot!

  4. I had the exact same problem as you right now. I installed some shitty "speed up your PC" software that set the tooltip timer practically to 0 and it was annoying the shit out of me in Eclipse.

  5. Thank you sooo much.
    I like Tweak UI and usually I like tool-tips appear quickly, but in an IDE it becomes a nightmare. I just didn't realize Eclipse was impacted by this setting too.
    BIIIG thanks!
