Thank you for checking... Good to hear that it's working for you. I
suspected that something could be wrong with the way I'm building it,
but all my other tests (and the entire application) are working
without issues. I'm building lua with the same command; although I
used a copy from one of the previous builds, but none of the lua
settings have changed. I'll do some further testing, but so far my
builds still show the same issue.
Paul.
