Fireworks CS5 Version 184.108.40.206 -- Just installed Mavericks on my iMac and now when I am working on a png and want to export it as a jpg, I click File>Image Preview, choose my settings and click Export. Then I get either a prompt saying "Could Not Save This File. The file was not found." OR "Could not save the file. The file is already open in another application." However if I continue as if I did not get a prompt, the file does get saved and exported. Anyone know what might be going on?
