I've been using Display Fusion for a few years with great results. It's helpful when I'm reviewing multiple documents on my 40" monitor, to be able to quickly resize and move them. For some reason, it stopped working. Windows can be moved to the approximate position, and are roughly the right shape, but they do not maximize to the split. I'm working with a bunch of PDF docs, and it significantly impacts legibility. I'm haveing to manually resize every open window. Help!

Brilliant! It worked!

Thanks so much for the amazingly fast support. You solved a problem that's been exasperating me for weeks, an hour after I asked the question, and you nailed it on the first try. Thanks!
