Windows 7: Quickly hide Tray's hidden icons menu?

The little popup box in the tray that comes up when you hit the up arrow (to "Show hidden icons") is bugging me. It seems to have a timer built in that hides it a couple seconds after you click on one of the icons inside. This really bugs me. I would prefer that it either hide itself immediately after I click on one of the icons (but not if I right click one, obviously) or else lets me hide it by clicking directly on it somewhere. I know I can hide it by clicking on the arrow again, but some of my tray applications (namely my Portable Apps Launcher) minimize again if I click that arrow, leaving me with no other option than to wait for that annoying box to hide itself and get out of the way.

So is there any way I can either set it to hide immediately after clicking on an icon, or to close when I click on the box itself? I'm sure there must be some registry value i can change or something to do that. Thanks!

I think some of must have thought I was posting instructions or something... But thanks for all the rep I guess haha. I'm still looking for help with this

I am not advocating this solution. By that, I mean I think I found what you're looking for, but am not personally willing to try it

The Taskbar Activate page

Thanks for the quick post post, but not quite what I'm looking for. I'm having problems with the tray pop out menu, not the taskbar itself.
