The browse table lookup appears behind the form

I made an application with c 11, when the form is stuffing lookup to another table, problems arise, when pressing lookup button, browsing the lookup table appears behind the form.
can anyone give me a suggestion, to browse the lookup table is in front of the form…

The instructions given will be greatly appreciated by me. Thank you

if you write

OPEN(Window)
0{PROP:Hide} = TRUE

then when you want write

0{PROP:Hide}   = FALSE
0{PROP:Active} = TRUE

Probably, MDIChild option is missed for the lookup window?

in true condition, for MDI
