### Scrollbar

Dear, tell me, please, is the scrollbar controlled by the mouse wheel, if so, how?

### Re: Scrollbar

Tell me what you exactly do so I tell you if that applies to your specific case.

### Re: Scrollbar

This code doesn't work because many variables are undefined, plus you did not put examplary values to call SlideShow function.

### Re: Scrollbar

Yes, it will not work that way, because there are many connections that are tied to certain paths.
I'll put it together to the bare minimum and, if you'll excuse me, I'll post the code tomorrow or the day after tomorrow.
Thanks for your attention and help!

### Re: Scrollbar

I tried it and roll handling scrollbar doesn't work correctly indeed. It moves it slowly (only when hovered) and doesn't change content of panel.

Most likely you met limitations of ScriptUI. The same is about cut bottom row of images. If other values used don't work then it is another bug.
