My first post (I think). Thanks for a great tool... until now 1 crash here so far. Now it's forcing a check of 100+ GB data... gonna take a while! uT told me 1.7.3 was available, so I updated "automatically" from 1.7.2. During the install I got something like "Unknown error" which I of course didn't save. I simply downloaded 1.7.3 and installed it by hand. Running only for a few minutes it crashed: Process Explorer file HiJackThis file Crashdump file I'll let it check my files and leave it running. If it crashes again I'll revert to 1.7.2. While writing this it crashed again... back to 1.7.2 I go. Cheers - avizion
