I'm still in my testing phase of 4.0 and noticed that when I went to modify a WAV file that I no longer had the option to choose an extension for recording. When you open the WAV Editor the only option that was selectable is "PC/Multimedia". Then after stopping an restarting the VM Pro Client a couple of times nothing changed then all of a sudden I now see "Telephony Handset". It has been very inconsistent. Has anyone experienced inconsistencies with this? There doesn't seem to be any rhyme or reason as to why this happens!
