after unlock, volume should restore previous state, not unmute about monitores HOT 8 OPEN

Thanks for reporting. Able to reproduce.I'll fix it.

thanks for the prompt response!

BTW, is the source available? What I've seen here seems to be a bit outdated; 
it seemed like an easy enough fix, and I wanted to be able to send you a patch, 
not just a report.

I almost forgot.I'll update the code today. Thanks for your help.

thanks for the code update, although I think you may have missed resource.h

Oops, my mistake.Updated code.Please let me know, If you would like to join, I 
can add you as a contributor :) 

and log.h? ;)

You know what, I committed the latest version(dev version) which includes all 
tnhose. You don't need log.h(just remove it from functions.cpp)

Just noticed that. Also volume.h is not required. I'll probably be sending you 
a patch soon.
