I use ZA for years. Had no problems so far.
But now (I can't remember if it already worked on Win7) ZA doesn't start automatically after booting.
I got a message that I should upgrade to the newer version 'cause a G... (can't remember the name) trojan or something can infect the system. So I downloaded the new version.
Now I'm using german version 9.2.058. When I start ZA manually it works. It neither works when I put it into the startup folder.
