Get rid of ZoneAlarm, It has a BIG memory leak (at least the free version I have does) which is a real issue if you like your LOMAC! I found it to be quite shoddy, I keep it for making internet calls as norton conflicts with that.
Also, I find ocasionaly that if I am not connected to the internet and I am playing lomac sometimes it switches out to the desktop for a connection prompt. Which is annoying and I thought it was spyware doing it but it might be lomac as you describe.
