I have a Fireworks CS4 document with a Master Page applied. If I right-mouse on an image slice and choose Export Selected Slice, Fireworks fails to export anything. If I switch off the Master Page (Reset Master Page) the image exports fine. I have tried the same scenario on another document (i.e. with a Master Page) and the export works. Either there is a strange setting on the first file, or Fireworks has got confused (it is a large file that I have been working on for a while). Any ideas what is happening - either expected behaviour, with a setting, or how to efficiently "reset" my document to a "clean" state?
