I'm running 12.5 on a host computer and trying to connect (TCP/IP) with my handheld.  It seems as though it's trying to connect but all I ever see is a black screen on my handheld.  The host says it's trying to connect then times out.  I tried using the same settings and connecting from another desktop (TCP/IP) to the host and it works fine.  Is there something I'm missing?  I'm not terribly technically savvy, but thought this would be simple.
