Sorry, yes, I did mean .ini
Silly little typo of mine.
I currently have 16 script files (I like to seperate as much code into different sections as possible), and they are all .mrc files.
As someone pointed out, the file in question is at the lower end (its the 14th script) of the "food chain", so I suspect this could have something to do with it.
Anyway, cheers for the replies
