I was just working with the (Designer, Project, Properties, Client, Launching - Screen Index) function with a dual monitor Windows Vista x86 client using version 7.3.4. I can’t seem to lauch a project in full screen mode on any monitor but the primary. I’ve tried index values 1-10. I’m curious which OS’s would support the index functionality? Thank you, Casey ---

I tried this same setup within a multi-monitor Windows 7 x64 client this morning and the screen index selection works as desired opening full-screen ignition clients on the monitor of choice for the project launched. ---

Thanks for the report - we currently have a ticket in our bug tracking system to improve the reliability of the screen index feature.
