Skype & UltraMon

So Skype has a custom skin for the interface. Skype's entire interface is painted from some sort of proprietary function or method. As such, applications which modify or add extra interface options or buttons may not display correctly on Skype's interface.

UltraMon is just one example. Skype loves this interface so much, they normally hide the ability to disable this "custom skin".

Screen Reader Mode - Disables Skype Custom Skin

Thankfully it wasn't too hard to find in this latest version [5.8.0.154], but was mistakenly listed as "Screen Reader Mode".

That setting should read, "Disable Custom Skin" and when checked will result in properly drawn interfaces.
