3170 works fine while 3171 fails to run multiple instances..

Related to fix of 0021491 -- so assigned to Petr to look into it..

Verified on 3172 multiple instances of the same 3172 were able to run.

However closing 1 instances (File > Exit) closes all instances of MediaMonkey.

Not sure if this is relevant, but with build 3171, if 'Allow just one instance of MediaMonkey' is disabled, then occasionally after the PC goes to sleep:
- On resume, MM was minimized to the system tray (and didn't appear in the taskbar)
- On maximizing MM from the taskbar, the UI would not respond (as if there was something in focus in back of the UI like 0017431).
I haven't had a chance to look into this, and assumed that it was related to whatever caused this issue, but am noting it here in case it's relevant.

EDIT: I haven't been able to replicate this with 3172 so far.
