Well this may be related, it may not.
I reduced the file from 175mb to 114mb... is their an optimal file size range I should stay in? Or at least an upper limit I shouldn't hit?
I reduced the canvas size from 1200x7000 to 1200x6500... I read somewhere that 7000 is the limit and all kinds of instability occur after that.
Any insights greatly appreciated.
This happens to me all the time as well. Fireworks CS6 regularly fails at saving.
One thing I've narrowed it down to is that this will always cause save fails:
1) Create a new page.
2) Create a layer called "Foo".
3) On first page, create a layer called "Foo". Share that layer with the other page.
4) Try saving. It will fail.
I have a lot of pages in this project. Even with those conflicts eliminated, there's still some other unknown reason that causes save fails. Just now, I deleted objects in two different pages. Save fails. Sometimes I rename a page. Save fails. Sometimes I look at Fireworks wrong, save fails.
It's failed to re-open the file, which has freaked me out. But restarting Fireworks resolved it. Still, save is sort of ESSENTIAL to placing faith in a program which is the ONLY ONE that can read that file format.
I used to love Fireworks, back in the Macromedia days. But it's clear Adobe has never given two craps about it, even though it's a cool program for wireframing / templating, and designing. With all the save bugs, I might have to give it up. :-(
The worse thing?
I went to see if there were updates for Fireworks CS6.
The Application Updater fails after it starts updating.
