Just recieved this email from my Z3 supplier:
Hi,
I have some good news. Sanyo have come up with a soultion. There will be
a software patch available shortly (next few days) to fix the problem.
This is something that you will be able to apply your self and so not
posting of projectors is necessary.
I will keep you posted.
Regards
XXXX
