Did a bit of housecleaning on my two PCs, specifically cleaning the boot drives of all those pesky log files that grow out of proportions and temp files. For those of you using CCDStack you might want to check the location of the cache and temporay folders in your program settings as it defaults to a location in 'Document and Settings' on win32. I found a bit over 800MB of txt files, I assume generated by working on the stacks. I feel much lighter now
