Thanks for the suggestion but we cannot go down the Web Application Project route as that would require fundamentally changing our application in a way that would likely mean the rest would not operate correctly without even more modification just to workaround a bug in this one piece of software.
This is pretty major if you ask me and should really be getting resolved asap, or at least certainly getting an update from the developers on how far they are away from a fix (or if they have even started looking into it yet).
