Hi James,
Can you post an SC code reproducer for me?
I can look tonight.

So there is no way, within SC code, to fix it.

Horizontal scrolling is essential when there are many channels, but currently I can do it only by 2-finger scrolling, which a/ is inexact on my machine, b/ frequently gets stuck on sliders and c/ I can't be sure all the students have a touchpad or a horizontal scroll wheel. Note that this isn't TXMod's fault -- our ScrollView does not display the scrollbars when it should. It's a small oversight in our code but renders TXMod's mixer panel essentially unusable for more than, oh, 4 channels. (Well, you "can" stand on your head, gargle some peanut butter and manage to get around it, but that isn't "usable.")
