Processes being started but GUI won´t show.
I start the tor browser by a shortcut pointing to '...\Browser\firefox.exe'. After that firefox.exe & tor.exe processes are being started (shown in Windos Task Manager). Two possible cases:
A: After a couple a seconds the memory usage of firefox.exe rises from about 60 MB to ~ 90 MB.
B: firefox.exe stays at about ~60MB of usage.
In both of the cases the browers GUI will never show and Windows Task Manager lists no entry for "Tor Browser" under 'Applications' either.
Just 1 out of 15-20 attempt leads to a successful start.
Tested with Windows 7(64) and TBB 4.5a5 but had that problem with older versions as well.
