Purchased and installed HTML Editor v17 (b836) today.

Now every time I run it, I get a popup error box at startup:

(red X) "Cannot focus a disabled or invisible window"

Anyone know how to fix that? (have tried rebooting, with no effect)

Also, the previously reported bug does not appear to have been fixed:

Have you tried redownloading the software and then reinstalling?

Nope, hadn't tried that, but did now - no change - error dialog at launch. Program is still functional once the error box is dismissed, but there has to be a way to fix it.

After the re-install didn't work, I did another un-install, and then went and found where CC stored all the files, and deleted all that too. Then did a fresh install, and now it's happier. No more error dialog. But the copy BUG reported over 2 years ago still persists.

I would open a support topic.
