Since this missing tooltips was occurring on my Toolbar AS WELL AS my Statusbar(but the tooltips of no other controls had this problem) I put a beep statement in the mousemove event to prove that it was firing, since that is how I originate my tooltips for the statusbar.

This problem was recreateable, but suddenly disappeared, and I did nothing to my program. As I was closing browser windows I kept checking it, when I closed file explorer windows, the problem went away, and I have not since been able to recreate it. I had reloaded XP prior several times, and the missing tooltips problem was always there, but now its not, not even with opening file explorer windows. And I wasn't that low on memory. I guess I have to wait until it rears its ugly head again to determine how to recreate it.
