I would be surprised if these caused problems as you normally pass the call
back address in code at runtime, so any address would be okay.
Objects responding to window or user messages will not cause problems - this
is what the VCL is built on.
A call back is provided for timers and threads and is also used for keyboard
window event handler hooks - again these are heavily used by the VCL - eg
the main window message/event hadler is one of these, and so is every window
used in the VCL.
Must be something else, stuff if I know what though.
