I'm an avid user of F&R Robot. Great software.
I realized today that when search in the "recent" folder is enabled, it slows things down -- it could also be a because of specific file in the recent folder or something else, I Don't know.
More specifically, when I wanted to start the calculator and used the down arrow to immediately select the calculator, F&RR froze for about 3-4 sec. and then resumed. Like I said, the "recent" folder (C:\Documents and Settings\Administrator\Recent) did it... when I removed it, it was okay. Putting it back (in the "Search Folder" area) recaused the problem.
Thought I'd share that...
P.S. :Not that many files in the recent folder (around 30). I've got a P4 1.8Ghz, 512mb ram.
