I keep getting this error message every few minutes the entire time I'm on the Internet: IExplore System error. Code: 1400 Invalid window handle. If I click OK the window closes and I can continue - until it comes back. If I close it by clicking on the X in the upper right sometimes it will lock up the computer and I'll have to restart. Any help will be appreciated!!!

carol: this error proved elusive to pin down; found only this: it is indicative of a system-wide problem that should be temporary (e.g. resulting from a crash of one or more applications or services). invalid window handle error is raised by Windows if operations on a non-existing or invalid window are attempted. if you restart Windows, this error should not reoccur. if it does, you may need help from a software expert to test your Windows installation. let us know what worked for you...
