Fritzing only partly working on Mac


Steps I took that resulted in the problem:

I am using an old OS X V 10.7 on my Mac because I do not want my other external hardware to be incompatible with newer operating systems. Anyway, when I connect to the WiFi network at work, I find that when I fire up Fritzing, it crashes and brings up a message “This program has quit unexpectedly”. When I disconnect from WiFi and launch Fritzing again, it works fine.

Also, if Fritzing is left “open” for a long time, it seems to interfere with other applications and when I try closing it, it can’t close and I have to “Force Quit” the application.

What I expected should have happened instead:

Fritzing should work when I connect to the WiFi network and use it for commercial use. However, when I connect to the Wifi network after Fritzing has launched correctly, it continues to work. I use Fritzing alongside Eagle which is essential for my job, so it would be really nice if Fritzing works flawlessly please.

My version of Fritzing and my operating system:

Newest version of Fritzing v0.6.3 beta, and Mac Os V10.7.5

Please also attach any files that help explaining this problem
