After some time, I think after saving some files and waiting a couple hours, Fireworks CS6 says, when exporting somewhere
File couldn't be saved.
The file couldn't be found.
(My translation from German) Why should it be found? I didn't wanted to open it. Just export it.
This issue wasn't before I upgraded to OS X 10.8. Is it a knowen bug and is there something I can do to get rid of it?
Has the location of the file on your machine been changed since you first created it?
We are investigating this issue on 10.8.As a workaround Export can also be done by setting the export options in optimize panel and then exporting the file with File->Export
… hope after investigation will come an update. Unfortunately FW lacks of quality updates in the past!
