Marten, Thanks for the prompt reply. Sorry, i have not been on sim for a couple of days, so I am late with mine. You were right. I had tried a couple of gates but they must not have been the appropriate ones. Tried a couple more & all seems working.
Downloaded updated LSZH from Org Dec15. Has Sam xml. Tested with Zibo 738 and ssg E195, both cold & dark -- no gate movement. Sam plugin in plugins folder & library in custom scenery. Running XP11.30RC1, Mac. Unchecked auto in Sam settings & gates appear somewhat greyed out & do not respond to clicks. Any help/thoughts?
