Hi Aston,
Forgive the quick and dirty description... Properties of an application's
windows are controllable by the operating system or the application itself.
Allowing a different application access to the window is, generally
speaking, a violation of process separation. That said, you might look into
SIMBL. It allows you to inject code into a running process. Not as a
separate process, but it is possible to modify an already running process.
Hope that helps.
