I am using TB with several accounts (4 active and some special accounts without much emails). When searching for an email using F7 or Tools, I find that the system does not respond as it should. Just now I tried to locate an email and even specified the folder where I suspected the email to be. Once I press start, nothing happens except that it seems that the search starts with only stop and help being active buttons. No further response, no results - my impression is that the TB freezes. Looking at the task manager CPU usage goes up to 60-80% and sometimes higher. This seems to happen almost every time so I am now reluctant to even use the function, leaving me to manually search through all possible folders. Obviously this is not very efficient. Please help as this is a serious drawback to an otherwise fine program.
