I've got two questions: 1) How do I find out "theSlot" to be used for a particular screen on a multi-screen system? The only thing I could think of was to paw thru the 'scrn' resource #0 (documented V5 p. 127). 2) What am I supposed to set qType to? Inside Mac says qType should be ORD(vType). Huh? I'm programming in Think C, my Pascal is long gone. Thanks, Kevin Whitley kw1r@andrew.cmu.edu
