I cleaned up the cpointer viewport (m_port) code a bit, and related code
routines, and now check for a valid m_port pointer, so it shouldn't crash
anymore.
Curious that it crashed for you hmm, could be a bug in Qt 4.7 + mac, or
something odd hapening in T.
Anyway, the mouse tracking code has been simplified a lot now, due the cursor
on the canvas is purely managed by software now (the cursor on the canvas is
just a canvasitem like all the others)
If the problem is still there (not a valid m_port pointer in
cpointer::scene_pos()) then it prints a debug message.
Greetings, Remon
