Well, that's not exactly helpful then. If they're not interested in bug reports it's not exactly my problem, I guess. Was worth the try, though.
I tried using Bru File Manager to open a PDF on a Win 7, Ultimate, 64 bit machine (Reader X installed) and it worked fine for me.
Which file manager are you using?
Also are you trying on Win 7 SP1 or Win7?
