AFAIK, this has to be supported by application (and it is not by UWord a the moment).
AFAIK, opening CommandLine would do.

After addressing me on CommandLine and some experiment I've modified a bit UWord to open a file by clicking on it (after associating it with windows XP). I've just modified a bit the main with CommandLine and moved Load() from protected to pubblic (I hope there is no drawback for this).
Nice.
Maybe we could add a code to associate file extension too? (And eventually, uninstall it).
