Cannot "pick up" the right "White Level" slider in stack histogram

[roelb]

Latest version 4.0.9011
In the "Live Stack Histogram": when picking up the "White Level" slider and slide it to the far right, I cannot pick it up later to slide it again to the left.
This occurs on my MINI PC.
On my laptop their is no problem.

Hi,

interesting...

Does changing either of the 'Log' or 'Zoom' settings for the live stack histogram have any effect on the problem?
Does the line you cannot pick up look thinner than the other two lines?
Does the cursor change to the <--> arrows when you move to/near the problem line?

I just had a go at breaking this and can't at the moment - tried different widths of the main window too in case that had an effect.

cheers,

Robin

It was probably with zooming without to first shift the x axis completely to the right.
So my mistake!
