Popup Menu Hot-Keys are blocking other gadgets

Here's a strange one (again Win32MaxGUI): when keys are declared as hotkeys for popup menus (only for them), the input on textareas is blocked for these specific keys.

SuperStrict


Local wnd:TGadget = CreateWindow("window", 100, 100, 300, 200, Null)


Global mnu:TGadget = CreateMenu("popup", 0, WindowMenu(wnd))
 CreateMenu("blub", 1, mnu, KEY_ENTER)

Local txa:TGadget = CreateTextArea(0, 0, ClientWidth(wnd), ClientHeight(wnd), wnd)
SetGadgetText(txa, "Try to begin a new line in here!")


Repeat

 WaitEvent()

 Select EventID()
  Case EVENT_WINDOWCLOSE
    End
 End Select

Forever
