I have had CS5 for a while now, but last night I noticed something weird with a particular image. It's a 16 bit .tiff (fairly big at 350MB) and when I tried to crop it it dies in the ass. After a lot of head scratching I found I had 1MB of C: left (out of 350GB) It has obviously stolen 350GB from C: as temp ram I assume, but here's the weird part. I have a second 1TB drive which I initially set up as a scratch disc and it also "steals" 160GB from that disc!! It only steals it when I try and crop, up until then I have all my HDD space as per.
I shut down PS and I get my drive space back. This is only new as of last night, it's been running ballistic up until then. I have 12 GB of ram which PS is allocated 50% of.
I thought it was the one image causing all the grief, so I tried another .tiff (86MB) when I cropped it I lose 160GB of drive and crop function basically freezes.
I usually do this and it is instant. It will open the 250MB image faster than I can blink, but since last night, when I crop it (or try to) I waited up to 10 minutes and finally gave up.
My system is an i7 920 with 12 GB triple channel 1600 ram and C: is a 10k rpm WD, scratch disc is a 1TB 7200 rpm seagate. The system is fine, it's something that PS is doing which is clogging it up and stealing all my resources.
Any help would be greatly appreciated!
