I have the G0593 8in jointer and I agree about the fore and aft movement of the fence. I can get it to work, after loosening the mechanism and "helping it" along. The track doesn't work well for me either. Truth be told I see NO need for that feature and leave it set at the full 8in width.
As far as making 45-degree surface cuts/joints, I use the TS and/or my MS for such things. The function on my jointer for 45s works just fine. I just don't use it for that. I leave the fence set at 90-degrees and full width.
