Well, it seems to be a larger issue than MS Chat. Any multi-line text with a hard return to the next line of text causes problems.

i.e., the following is sent:

test
test

When sending using mIRC, it results in Two new messages; each line it's own message:

[timestamp]<username>test
[timestamp]<username>test

Or is that what you're referring to, where mIRC parses the /r/n into a new message line. So that the test above will always result in two messages as opposed to what I see resulting from MS Chat sent messages:

[timestamp]<username>test/r/ntest

If so, how can I script mIRC to parse the /r/n message from MS Caht properly, or has someone already done so?
