    MouseHover even and windows 7

    I'm working on an application that uses the MouseHover event to display a tooltip balloon. This works fine in XP and Windows 7 Pro, but it fails to work on Windows 7 Home Premium. I don't have any experience using Windows 7. Does anyone have any ideas what might be going wrong? I've already checked .NET versions are correct to support MouseHover. The win7 home premium machine user has admin rights.

    Have you debugged the program, setting a breakpoint in the hover to see if it's actually being fired?

    As I see it, you have two possibilities -- that the event isn't firing, or that your tooltip balloon isn't showing up.

    Can you give a small sample code that illustrates the problem? I can test on my Win7 machine.
    You ever try a pink golf ball, Wally? Why, the wind shear on a pink ball alone can take the head clean off a 90 pound midget at 300 yards.

    Unfortunately, the machine it doesn't work on is the client's laptop and I don't have access to that, other than installing the program on it, so no compiler. My co-worker and I have a development laptop with win7 pro and everything works.

    I don't think the code is the problem since it works on XP and all win7 machines we've used except the client's. I'll just tell him to get another laptop.

    Currently we worked around the problem by using a click event to display the info. Thanks for the suggestion though. This is one of those glitches that nag at you so you HAVE to find an answer.
