I recently found Lyx and must say that it's features look very promising. However, I find that when using the View menu, and selecting either PDF or Postscript, my system frequently locks. When this happens, both screens (I'm using Xinerama with a G400) blank to power saving and the system is utterly unresponsive. I've attempted remote connection to the system over the network during these lockups to no avail. The only recourse I've found is cut the power. Obviously this is highly undesirable.
Any ideas?
