On Mac OS X 10.6.5, I'm using InDesign CS5 Version 7.0.3 with MediaBin 4.6 Build 25 & also in testing MediaBin 7.2.2. In both versions of MediaBin, the user has to zip the InDesign files while downloading them from MediaBin order to then be able to open them in their local version of InDesign. Otherwise the system downloads a simple thumbnail with no file attached to it. I've seen some mentions of an InDesign plug in for MediaBin. Are any of you familiar with this plug in? What does it do? Does anyone know if it would provide a solution to this problem? Is/are there other reasons for this problem?
