We have this if we build on one particular portable (so we try not to). The usual cause is that there is a drive letter embedded in one of the files in the project or within the project itself. It could be a Screen, Report layout, anything. About the only thing you have to go on is whereabouts in the application it fails. What's really needed is a wild card search and replace that will run through memo fields.
