Version: (using KDE 4.4.0) Installed from: Gentoo Packages In the current implementation there is no way to know how long a voice clip can be until you use the time (15 seconds) up. Also you can't send very short voice clips. So together with the cancel button a progress bar would be useful that tells you when you have reached the minimum length of a voice clip and when you will reach the maximum length.
Hi there, sorry for the bad news, but WLM has been discontinued by Microsoft, so this bug will be closed. Thank you for helping us make KDE software even better for everyone!
