I disagree with these negative comments about APE. I've been using APE for at least 12 years and have never, not even once, had an issue with any of their software. I view their Fruitmenu and Windowshade utilities as two of the MOST useful, MOST essential productivity utilities ever. I've also never had a problem contacting their tech support nor with transitions to new Apple OS upgrades. I have not yet tried SmartScroll, but as far as I'm concerned, Unsanity is at the top of the pile of developers.
