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
