Working with Comodo Firewall

I have installed the Comodo Firewall Pro on my system.

I mistakenly marked Google Desktop as an Isolated Application (I do no know what it means even now). Google Desktop stopped working. I did not know what to do. I uninstalled the application and then installed it again (hoping that it might work), but it would not work. So, I googled in one of the forums I found how to change the status of an application. Then fixed it hope it works now.

All those who are new to Comodo Firewall may want to have a look at the link.
Comodo is an excellent firewall.
