Google Chrome: Problem with bookmarks bar?

[Paul in North Carolina]

This is an odd, of not completely irritating problem. When I am viewing a web page and I hover my mouse pointer over a given link on the bookmarks bar, a white box (providing the name of the link and the url) pops up over that part of the bar. That's fine. However, if I move my mouse fast enough over the bookmarks bar, the fore-mentioned white box pops up where ever the mouse happens to stop on the web page and will stay there until i move the mouse pointer all the way to the top of the browser and back down again. It is sort of hard to describe this issue, I know, but without posting a screen capture of what it looks like, I don't know any other way to say it. For what it is worth, I am using Win 7 Pro with Google Chrome 17.0.963.79 m. Also, I have completely uninstalled Chrome and reinstalled it, with the same results.
Any ideas?
