I have a main window which produces a number of child windows when I press a button. Users need to be able to switch between windows using Ctrl+Tab hot key. I was trying to implement this by intercepting keyup/keydown events in one of the frames. But the problem is that main window has several frames and I don't have access to all of them because some of them are in different domains. As soon as a user clicks on a frame without my handler the hot key is not working anymore. Any ideas how to implement it? Maybe an ActiveX component? If ActiveX could help me - how does it work? Thank you.
