I have an alias that concatenates three commands. Using the alias was hanging tcc.exe when trying to change to "My Documents". I have isolated the problem to "*cdd /T .". [C:\Users] >ver TCC 11.00.50 x64 Windows 7 [Version 6.1.7600] [C:\Users] >*cdd Charles\ [C:\Users\Charles] >*pushd [C:\Users\Charles] >*cdd "My Documents"\ [C:\Users\Charles\My Documents] >*cdd /T . The last command produces a "Location is not available" dialog. Clicking "OK" hangs tcc.exe.
