OK, I've found the problem and fixed it.
When you try to remember 256 in an unsigned char variable, you 
get 0 sometimes...

I'm attaching a patch---it's relative to the current version, ie. 2.5.1
but it may work with older version---I've not tested it.

Thank you again for your bug report.

With kind regards,
