Ok, I'm obviously doing something stupidly wrong here, but I can't seem to get EditWindow to work (Grid v5.0.20, APL v5.2.02, Win98). I've created a separate Edit control and put its hwnd into Edit Window. But if I try and edit the cells, it seems to be ignoring the custom EditWindow control completely and just doing its usual cell-editing thing. (IOW, it doesn't move my window and doesn't transfer keyboard input to it.)
Has anyone successfully used EditWindow before that might tell me what simple thing I'm forgetting to do?
