I agree with jaytea about the fact that a script can further be adjusted to work with the latest versions, but some people either don't know how or bother to do so...and as a result, they take the latest builds as a culprit that their old scripts have stopped functioning. As for buggy issues, not necessarily a user will encounter them if his or her main purpose of using mIRC is to chat and monitor their chat rooms. Some self-conscious folks will think a client with bugs should be avoided at all costs. Nevertheless, against all odds, the latest version should work fairly well for those who give it a whirl.
