98 * 3 10/09/98 2:57p Dave
99 * Starting splitting up OS stuff.
101 * 2 10/08/98 2:38p Dave
102 * Cleanup up OsAPI code significantly. Removed old functions, centralized
103 * registry functions.
105 * 118 7/10/98 5:04p Dave
106 * Fix connection speed bug on standalone server.
108 * 117 5/24/98 2:28p Hoffoss
109 * Because we never really care about if the left or the right shift or
110 * alt key was used, but rather than either shift or alt was used, made
111 * both map to the left one. Solves some problems, causes none.
113 * 116 5/18/98 9:22p John
114 * Took out the annoying tab check.

119 * 114 5/16/98 2:20p John
120 * Changed the os_suspend and resume to use a critical section to prevent
121 * threads from executing rather than just suspending the thread. Had to
122 * make sure gr_close was called before os_close.
124 * 113 5/15/98 4:49p John
126 * 112 5/15/98 3:36p John
127 * Fixed bug with new graphics window code and standalone server. Made
128 * hwndApp not be a global anymore.
130 * 111 5/14/98 5:42p John
131 * Revamped the whole window position/mouse code for the graphics windows.
133 * 110 5/04/98 11:08p Hoffoss
134 * Expanded on Force Feedback code, and moved it all into Joy_ff.cpp.
135 * Updated references everywhere to it.
