no prob! ty.
It looks like I forgot to mention in the original post that it seems to only happen when working with very small size images (like the 64x40 image). Maybe that can shine some light on what's causing it?
I noticed that the image preview on the right-hand side tends to get cropped incorrectly when using the "snap grip to image" feature. For example, this image that says "Hello" is 64x40 pixels. After I snap the grip to the image, the preview on the right side is cropped to only show the "ell" part of "hello".
I am running a fresh install of Texturegrub and have not changed any settings from their defaults (to my knowledge).
