Tabledit Issue

I've recently been having an issue with Tabledit: it will not allow me to use the "Print Preview" feature. When I click on the button, it simply doesn't do anything. It's a problem because now I can't print tablature I make. 

Has anyone else had this issue recently? I've updated Tabledit and restarted my computer, not sure what else could be causing it. It could just be me. 

I've liked Tabledit overall, but this has caused me to look into other options. Has anyone used MuseScore to tab out dulcimer music? It doesn't support the diatonic fretboard, but according to Google some folks have found ways to make it work.
