When I press spacebar for the fullscreen preview, then click (with my wacom tablet), I ALWAYS get a zoom to 800%. This is way too far! 100% would be fine. WHat's going on and how do I change this? It's nothing to do with the wacom pressure because it doesnt matter how light I press.*
The default zoom is 100%, but you override this by pressing plus or minus during full-screen preview, it then remembers the last setting.
Next time you do a full-screen preview, press minus a few times to get back down to 100%
