Update of /cvsroot/arcem/arcem/X
In directory vz-cvs-4.sog:/tmp/cvs-serv1065/X
Modified Files:
DispKbd.c
Log Message:
Allow use with X servers that don't support XWarpPointer. New environment
variable ARCEMNOWARP which invokes this mode of operation. Not very smart
and not perfect, but better than the alternative which is totally unusable.
