I agree with qwerty. I believe you have misdiagnosed this issue. There is no proof to support your claim that the cause is "most likely the wrong file path." There is, to the contrary, proof against this in that mIRC can actually access the popup script. If mIRC can access the popup script, what on Earth makes you think mIRC can't access the popup script?
menu nicklist would be far more appropriate. Please don't make a suggestion unless you have encountered this problem and are 100% sure you know how to reproduce it. I don't think a multi-user environment could cause this problem. However, I have had experience with missing menu items in many Windows apps (including mIRC) when system resources are low.
