Didn't see it posted here so i thought i'd let you guys know about a program that was posted about over on the sprintusers forum. Goto this page
here and download the program Clear Temp. It works perfectly for me on my mogul. Not only does it do the recent/opened programs in the start menu it also does the following.
Temp, Cache, Cookies, History, Opera/minimo/netfront Cache, Custom Folder 1&2, Large Mail, Mail Attachments, Recent Programs, Internet Addresses, Boot Count, Bad Theme Registry, Bad Uninstall Registry, Dead Shortcuts.
Definatly worth checking out, then you wouldn't have to buy memaid or do a bit of registry editing by hand either.
