what is the next step for winspww2?

[Rosollia]

is it possible to completely resolve the issue with program file path, or the issue with alt tabbing in full screen mode?

With the program file path issue, you can simply install the game outside of Program Files folder. Also if you turn off the anoying Windows UAC feature you can install and run the game fine even from the Program Files folder.

If you want to play the game in full screen and use alt+tab you could try the alternate fix that I posted here:

I have not gotten any feedback as to how it works yet for others but on my own Windows 7 machines it worked.
