TCC 18.00.16 x64 Windows 7 [Version 6.1.7601] I know this used to work but lately if I type a command name then press F1, an empty help window pops up, the main TCC screen goes foggy (as in non-responsive), then hangs. After a minute or two Windows pops up a dialog that "TCC has stopped working" and offers to restart/debug it. The same thing happens if I just type 'help' at a TCC prompt. Not sure when it started, but I seem to recall having the same problem with TCC 17 (which I just upgraded _from_ last December). I'm guessing it must have something to do with an Explorer plugin of some sort I am running, since there doesn't seem to be any other users reporting this issue. How can I diagnose/resolve this? I am tempted to install a trial of TCC 19 to see if it resolves the issue, but again, if I'm the only user having a problem it is probably with my environment and the new version probably won't behave differently.
