First off, don't really use Screenshot Captor, (sorry), but I thought I'd have a play with the latest version 4.03.0 and found a couple of small things:1)
In the options under Image File Format, a slight mis-alignment of the Compression Level text w.r.t. slider, I think the text max
needs to be a bit more to the right.
I'm not using any Display scaling or weird fonts, DPI, etc - just boring old Win7 default.2)
In the process of playing with the arrow object to do the above I found that if I drew an arrow in, then hit Ctrl+Z so I could put it elsewhere what would happen is:
a) the arrow gets removed,
b) the arrow object controls are still visible so you believe you're still trying to draw an arrow,
c) when you go to place an arrow you find yourself selecting an area and the arrow object controls vanish.
I would think that upon hitting Ctrl+Z either:
1) the object gets removed and you are still in the object drawing mode, (preferable), or
2) the object gets removed and the object controls get hidden at the same time so you know you're still not in that mode.
