Indeed, that can be fixed. Can you give me a sample code that how you
are going to use this API with multi-window? Even pseudo-code will
help me understand the situation better.
Currently the text input implementation is a bit broken for
multi-window since I only added a field edit to the front most window
on Cocoa_StartTextInput(). It can be solved once we switched to use
the field edit provided by NSWindow. I am working on it.
