This is crazy and I must just be missing something obvious. I settled down to learn Fireworks today for moking up html. I'm watching a tutorial. When it came to dragging things from the common library into my doc, it just doesn't work. The elements simply won't drag. No error. Just no reaction whatsoever. I have the pointer tool select. Everything is set up just as it is in the tutorial I'm watching. Works for him, not for me.
I'm using CS6, trial. I've googled for an hour and can't find anyone having this same problem.
I figured this out. Solution was to reboot and update Fireworks. Not sure if it was the rebooting or the bugfixes in the update -- or both -- that did the trick.
