Hi rharv,
I looked in C:\RealBand, and found the folder containing recently generated error messages, and this is the last one on the list:

(2011.5 (3) Beta (3)) 7/17/2011,5:42:01 PM -
Access violation at address 0074B821 in module 'realband.exe'.
Read of address 00000064 at: 0074B821

When RB comes up, the main screen initializes - there are no open windows - it just locks up right there. There's nothing I can do but use Task Manager to kill it.
The program leaves bbw2 running with about 50% of the CPU cycles encumbered.
The message about bbw2 running is hidden behind the 'desktop', so you won't know about it until you attempt to shutdown the PC.
