Version 1.3.18 released
I have just released a new version of QTM. This is a minor release, and simply removes the "system tray double-click function" preference on Unity, because the system tray on Unity does not allow more than one mouse click function (the equivalent of a right-click on KDE or Windows). Anyone using the package of QTM supplied by Ubuntu is encouraged to upgrade by installing my PPA, as the Ubuntu version does not feature the Unity launcher menu.
Source downloads are available by clicking the links in the box on the right; since this only affects Ubuntu users, only Ubuntu binaries will be released.
