I installed EQS on a virtual machine running XP Pro SP1 a few hours ago. It popped up a message a few minutes ago saying "out of memory". I noticed that almost all the paging file is being used and I have never seen anything like this amount of paging file use before on this virtual machine. So, EQS uses gobs and gobs of memory? Being a VMWare Workstation 5.5 machine this machine doesn't have a lot memory but EQS should not be a memory hog either. The virtual memory size for EQ is GIGANTIC. Why? I certainly won't ever try this application on my host machine! edit: I just shut it down and the page file usage dropped instantly by more than TWO THIRDS! The machine had been very sluggish ever since installing EQS. Now it is back to it normal snappiness. How come I was able to shut down EQS totally from the systray? I see no driver still running. That is bad. I should not be able to shut it down...the GUI maybe but not EQS without uninstalling it.
