So I *want* to keep that box ticked and yet still have tool tips work.

AFAIK, the utlity I mention here is the only thing that allows me to achieve both of those.

That said, you’re right and I think it’s worse than that actually. I believe it may have some sort of memory leak and grabs more memory over time. So if you habitually hibernate or go to standby instead of actually shutting down and rebooting, it can turn into a major memory hog (like 37MB instead of “just” 7MB). Seven is already a lot, of course (same as the MYSQL daemon and almost as much as Google Desktop), but 37MB is a little out of control for what it does (that’s about the same as Internet Explorer which is about half the memory load of Firefox).

Really Microsoft should fix this and and it should take little or no memory. Barring that, this is the best fix I’ve found. Obviously, whether or not you use it depends on how aggravating the problem is. For me I have a couple of apps that sit in the system tray and usually I just want to hover over them for a status report. Impossible with Windows messing up. So for me it’s worth it.
