I just upgrade to CS5 FW and DW. Did my usual export from FW to DW and one.... only 1 slice shows up as a blank grey square. Can't seem to do anything about it. The others appear normal. The others that appear as they should (invisible) are also accompanied by a drop down menu. I tried adding a swap image to state 1 and it did nothing. Please help. Here's what it look like with the blank square which is the exact dimensions of the FW slice.
Check to see if it is an HTML slice
It is created from Fireworks. My work around has been to redo all the pop menu.... quit laborious. But, then it works fine. Any suggestions are much appreciated. I have two sites that I constantly update and it would greatly help me redo the whole thing work around.
