G'Day. Adding my 2 cents worth as well. Upgraded to 4.06, totally unable to save alpha/primary and depth files to any folder other than the Vue/pictures, and even then "disk space errors" were occuring, plenty of space, 30GB and 79GB on other drive. Went back to fresh 4.00, upgraded in steps, 4.01, 4.03full and 4.05, had to do this as I purchased 5 plants form Vue online, and totally unable to load them as per their doc, thus the need to try each upgrade till the damn plants would create/load properly. Anyway, plants are ok, saving aplha's works fine to other drives, folders, also 4.05 is faster than 4.06 for finding files, mixing mat's, slower than 4.00 and 4.01, but I needed those plants. I'm am sticking on 4.05, and will probably stay right there. Sorry for the gample but thought it might help. Best wishes to all. Gary
