1) If I paste a line that's too long, it would be nice if mIRC at least warned me that it was cut off (preferably indicating where: "Your message was cut of after '...this is very'"). I often paste long error messages and then get told "I only saw it up to..."
This is something that mIRC doesn't know. The server is what cuts off the lines, and every server uses a different legnth. The way I have solved this, was to make a script that automatically splits my lines into 2 or more lines if they are too long.
2) I'd like an option to keep mIRC from EVER sending lines pasted, without first prompting (if > 1 line) or just leaving the data on the input line.
Done with the "confirm paste" feature
