When I use the font "Arial Black" in PSP8, then try to adjust "leading", the font goes wonky like this:


I haven't noticed it do this on any other fonts. Does anyone have any idea why it's doing this, and if so, do you know how to fix it? If not, is there perhaps another font that looks similar that I can download and use in its stead?

Thanks in advance.

EDIT: All I had to do was turn off "auto-kern". Try it if you're having the same problem.
