>Maybe the first service pack will correct it, but if it doesn't, I guess the only work around will be to NOT set the Always On Top property to true if you plan on using tooltips with a form that is also the Top Level Form. I assume the basis of this problem can (or will) cause similar problems, but I haven't had the time to really sit down and go through it all.

Probably that's not a very important bug, since it's not common to use more than one top-level in an app (I only use them as a more controllable version of the main screen), and hence Alwaysontop isn't too meaningful. Still, a bug is a bug is a bug...
