Thanks for that. I've downloaded v19.1 and cannot seem to get the OnDoubleClick property to accept a value for either manually created controls or controls created in nomads.
0010 LET MY_MULTILINE=5
0020 MULTI_LINE MY_MULTILINE,@(50,5,10,1)
0030 LET MY_MULTILINE'ONDOUBLECLICK=5000
Results in an Err #88.
Have I missed something?
