What a piece of SH!T this app is. I tried a while back to use it on a laptop with dual core proc and 2 GB of RAM and couldn't even get one router going..Crash...Crash...Crash! Now I'm trying again to get JUST ONE ROUTER up and running on my desktop here at work with 3.5GB of RAM and still the same thing. I have read and followed the tutorial on the GNS3 site and still I can't get it going. When I try to open a console session it just sits....sits....<press enter>...<press enter>.....sits...sits....CRASH! I really would like to learn how to use this so if anyone has any suggestions I would greatly appreciate it. Sorry for the rant.
