Two GuiSliderCtrl Problems...

I have a few vertical sliders doing the volume stuff...it works fine, but the visual aspect is a bit lacking.

First, the sliders are upside down; that is, pulling the tab down makes the volume go up, and pulling the tab up makes the volume go down. Sounds like an easy fix. I hope. :)

Second, when the slider tab hits either end of the slider, it gets cut off a bit on the ends, I guess because it is reaching outside the bounds of the Ctrl. However, resizing the control also resizes the bar. Any suggestions?

Thanks,
