If I try setSkewFactor on a slider, my plug freezes when I touch the slider. Does it change the sliders behaviour in some way, with regards to change messages or something?

this might not be it but i came across a bug with setting the skew factor - it would cause an exception, which didn’t freeze my plugin, but you never know…

there’s a fix here:

hope it helps

That might be it. I’m working around it for now, but I’ll try it out.
