[tor-talk] Any problem installing TBB & Vidalia bundle on same machine?

[Joe Btfsplk]

My question involves 2 scenarios.

1.  Installing both TBB & Vidalia bundle, so other apps could be 
torrified if need to close Tor browser.

2.  Install & run TBB & Vidalia bundle simultaneously, so if close TBB, 
don't have to wait for Vidalia startup to torrify other apps.

Not sure which of these would be more common, at present.

Tor Project is moving away from Torbutton, which is fine - urging use of 
TBB.  Sometimes I may not want Firefox in TBB open, or may need to close 
it, which closes Tor.
But, may either already have other apps running, using Tor, or want to 
start them quickly.

Is there a problem using both - either separately (one active at a 
time), or simultaneously?

Last, for non browser apps, is there a standard way to check if they're 
using Tor (say, Thunderbird or other apps), as the check for browsers?
