Hello, While not directly train related I am having a major issue with Quicktime locking all *.mov files such that I cannot delete, move or rename them. Has anyone run into this and if so what is the solution? I un-installed Quicktime which unlocked the files but then when I tried to run them in RealPlayer it said I needed Quicktime installed. The message I get is: Cannot delete <file name.mov>. It is being used by another person or program. Close any program that might be using the file and try again. then the "OK" button. Well, no, it most definitely not ok.
