Thank you,
first, ps_x is my writing mistake,sorry.
When right mouse click i`ve got the background with buttons,super:)
But i lost mouse poiter so now i am unable to highlite or click on buttons.
I use A5_template_project in my test.wdl.
When "uninclude" player_selection.wdl line, in test.wdl ,
i get mouse pointer back.
What to do next?
