Tootler - thanks but I need to have open a number of Mac-specific programs at the same time as the Score software, so that's not an option.

Slim - Yes, thanks I knew that and have been in discussion with them. This issue's been kicked around for a while, but no-one's found a work-around yet, or looks likely to - soon enough for me anyway.

I'm trying to find something else that won't break the bank and imports midi files on a Mac.
