Photoshop won't release RAM

Can someone with more experience shed some light on why CS5 doesn't release the RAM it was using when I close the program? I don't have a problem with it using as much RAM as necessary when I have it open. I noticed tonight that my computer is still super slow after I close Photoshop. I look in the task manager and see that it still has over 2 GB being used by "photoshop.exe" even though I closed it over 5 minutes ago. Is it normal for it to not release the RAM afterwards? If not, what settings do I need to tweak?

My Google search only yielded people complaining about all the RAM it uses while open.

Thanks

Its a bug in PS, the most up to date version should be better, but I have have problems with it.

Not often, just sometimes, and usually if its been open for several days.
I just open task manager and kill it, easy fix.

I should be up to date too. Killing it via Windows is an easy fix and I've been doing that. Thanks a bunch for the info.

Plus, all versions of PS seem to have file allocation problems. Even after an image is closed, periodically a file cannot be moved, renamed, etc. Same solution: end it. Frustrating, tho, that you have to close an app to get your file system and ram back. You think Adobe would have fixed it thru the years.
