Hi, Chris, thanks for the tests.A good old fashioned bug in DPScan may be the cause, say a dependency on the contents of a memory location. Perhaps an illegal address or one that is not being correctly initialised.
I'll do a test version that will explore these possibilities.I think one interesting point, is that Martin seems to have located the bug at the same point in the code as the original user. The point being that Martin has a production version, whilst the user had a "debug" version with function names in. That means the code is at different addresses.
Do we know if save to another application crashes - this won't work with all file types, but a save of a file in sprite format to Paint should work.
