#294 avoid multiple instances

[Antarctis]

Hi all,
I have a Windows machine which I use also to access remotely with Terminal Services (Remote Desktop that is). Good practice or not, both sessions are run as Administrator. This means there will be two instances of Clam Tray, which at the beginning I found fully ok. Now comes the problem: as I have a scheduled scan running at night, BOTH instances will try to scan the computer at exactly the same time. You can imagine the scans are take MUCH longer and are rendering the computer almost useless during their run.
I guess the scan could be a bit smarter to check for that and make some sort of appropriate decision what to do...
Thank you,
A
