A function call has been made to an object that is invalid

[Slap Happy Larry]

Would it be possible for you to send the failing ptg file to [email protected] (either a link to a downloadable file, or the actual file if it's not too big)
I'd like to take a look and see why it's failing.
And can you give me any more information about when you're getting the crashes? I'd like to try to reproduce the crashes here so I need to know what kind of things are likely to cause them.

Thanks.

Thanks Andy.

Sorry, just realised I sent it using your [email protected] email address. It's a link to Dropbox.
Cheers.
