Hi there – I stopped keeping Magelo Sync running in the background a couple years ago because it seemed to be chewing up tons of CPU power. I accidentally left it open again and noticed EQ lagging. I checked Task Manager and there it is, using up every spare cycle.
I opened up two instances of Magelo Sync to see if the problem was that one instance was just open for "too long", but it looks like, together, the program will use up whatever unused processor power there is.
