Chuck,
Actually that is usually due to what you think is an exact match, not being one.
For instance, tabs instead of spaces. Or an extra space at the end of a line, or a carriage return when there isn't one in the actual file. MultiHack searches for an EXACT match other than case. I honestly haven't seen yet where one of the above(or something like it) was not the actual problem.
MCSEguide, I'll get back to ya tommorow. My air conditioning died today and well, almost 600 bucks, several hours and it is now fixed... anyway, I'm going to bed. But I can test on that platform so I'll let ya know what happens.
