Mumble hotkey problems

[JudgeLazar]

This is a minor problem but very annoying. I have set my keys for mumble properly but when I use my teamspeak key (mouse 4) mumble picks me up even though mouse 4 is not bound anywhere in mumble. I have not been able to find anything on google and am at a loss. Sometimes I want to communicate to my friends in TS without everyone around me hearing it. I don't even know what channel it broadcasts on.
