Hello, I am having a bit of trouble with a script. not sure if this function is supported in Windows 7 but here it is. I have a volume control slider, when I move the slider the volume mixer's slider moves but the volume does not apply. This works for Win Vista (all ver and arch) and Win XP (all ver and arch) the code I am using is SoundSetWaveVolume(GUICtrlRead($Slider1)) Would anyone be able to help me with this issues? Thanks, Tom.
