CapricaSix - 2013-06-03

Last night my PTT key was operating correctly, being suppressed from all applications besides mumble on my Windows 7 machine. As of today it does not (version 1.2.3 Mumble). I updated to 1.2.4 and it still does not suppress in other applications. This behavior is also present on my Vista machine and has been for months, I assumed this was a result of Vista's quirks. Any idea how to fix this? I've tried running mumble as administrator and uninstalling / reinstalling. Thanks in advance.
