The Edit / Resize Image (or canvas) dialog looks quite weird in Windows 7. Especially since the "Add a uniform border of size" textbox is completely out of sight...
I am using Windows 7 Pro, 64 Bit and Screenshot Captor 4.13.0
I just downloaded the latest version of SC and it seems to be getting better and better :-*. I especially like the (new?) "pixelate inside selection" command in SpecialFX1. Would it be possible to add this to the available toolbar buttons in Options->Advanced Tweaking -> More Interface Options? And while you're at it, you could do the same for "Splice out strip defined by selection - Deluxe effects".
Since a few versions the thumbnail-pane seems not to scroll down automatically anymore. This is a minor annoyance as the thumbnails are sorted "latest at the bottom" (which is not changeable to "latest at top" by the way) and so I always have to scroll down manually to see the latest screenshots.
