Sorry for the slow response, JoWie. I wanted to do a search through bugs.winehq.org/ rather than say, "I dunno." Searched for "openprocess", "continuum", and "subspace". The answer is yes, and no. The closest report to what you are talking about is here: http://bugs.winehq.org/show_bug.cgi?id=22006 . It looks as though nobody gives a flying fuck, since the bug has been open for over four years. It's also mentioned here: http://bugs.winehq.org/show_bug.cgi?id=21702 although that's not about OpenProcess so much as Continuum acting up. I have to also say I don't know what all this "OpenProcess" and "PROCESS_VM_WRITE" stuff is. My programming knowledge is just enough to get by with computations in Mathematica, MATLAB, LabVIEW, and VBA Edit: Tried to fix the second link, but I can't figure it out.
