the change of the slider can only be detected after mouse up ('value changed' condition). While moving the slider around there is no way to get the actual value.
This also happens with the Slidercontrol-ActiveX.
The possible workaround:
-set counter to slider value
does also function only after mouse up.
The volume control in the task bar provides immediate update, which is necessary for volume changes.
It is possible to add this feature to the taskbar object, please?
