I have a Macbook Pro - OS X version 10.6.8 4 gigs of RAM. Okay, I noticed that my mac was running REALLY slow. So I opened up my Activity Monitor and I noticed that when I would searched for .xcf files that GIMP would open up multiple times in the background. So many times that it would lock up my computer. The problem is that anytime that I open up a folder with XCF files in it, GIMP again begins to open up multiple times in the background and locks up my computer. HELP!
