Hi Christopher,
You also might check your multi-processing mode.
Your call to pfMultiprocess (pfMultiprocess(PFMP_FORK_DBASE |
PFMP_FORK_LPOINT);), means that you do not fork the CULL and DRAW
processes, a must for dealing with multiple screens.
Try pfMultiprocess(PFMP_APP_CULL_DRAW | PFMP_FORK_DBASE |
PFMP_FORK_LPOINT);
My .02 euro.
Dick.
