Downloaded and installed over the top of my existing setup

I am still running a whole bunch of other applications here including Mail, Skype, Web Browser and twelve other utilities.

And the memory use is very light

Because I have the 

ghostios

and 

 sparsemem

enabled the memory footprint is very small.

    Heh, try running bgp on those routers, it will eat up your PC, you, your fridge, or anything that is in 100 meters distance

    I’ve run into memory leaks most times I’ve used GNS lately which is a shame. Hopefully they’ve improved this in the new version

    Well, my project file did not load after upgrading to 0.7 because it contained a PEMU PIX. I had to create a new project with a PIX, then add a license key, then cut the resulting project config, then insert it back into the original file.

    [pemu localhost]
    section had to be changed to

    [qemu localhost:10525]
