Change Text Size in Skype Chat

It's not the 'cleanest' solution but it works.

While you are talking you can go to: Tools -> Options -> Video settings

Then you will see a button labelled "Take a video snapshot". Click that and It will give you an enlarged version of your video.

You can then close the Options window to get it out of the way.

It would seem that the problem has to do with Windows 7. When opening Controll Panel -> Appearance and Personalization -> clicking Adjust screen resolution and change the size of "text and other objects" from 125% to 100% all of the skype windows aquired the same (small) size. Strange behaviour...
