Skype suddenly kept crashing on my at launch.
I figured there must be something in my main-system that makes this happen, since Skype did run perfectly on my backup-system.

I simply tried disabling every .ape and extra extensions installed, and found out that WindowDragon.ape was causing Skype to crash.
I solved this by adding Skype to WindowDragon.ape's exclude list, meaning WindowDragon.ape should not load for Skype.
Skype now runs perfeclty.

So if you are having any problems, try disabling all extras installed, try Skype and start enabling those extras one-at-a-time.

Thank me for being such a good hacker!
