--- Comment #6 from Matthew Flaschen matthew.flaschen@gatech.edu 2008-09-26 08:29:12 --- I spent a while hacking on this, and at least I can say I understand the code in question better. I noted that SC_SCREENSAVE /is/ processed by explorer/desktop.c (http://source.winehq.org/source/programs/explorer/desktop.c#L68), which calls start_screensaver in the same file. This works on my system.
However, Wizmo still does not, and I have not determined why. The code I used to test the screensaver functionality is attached.
