Cant press save in form editable grid or form editable grid (view)

i am using scriptcase 9.12.0028 hosted on scriptcase.host
in form app (in orientation), if orientation is editable grid view or editable grid , save button doesnt get clicked (gets frozen)…

but if i use same form in single record, save button works perfectly.

there is no event code (after before insert/update code) nor any program . just one ajax which calls a simple php program.

some scripting error am i missing or is orientation editable grid a bug?
