there's no alternative theme when clearmsn theme is unchecked. it defaults to mirc's built-in theme, so there's no "on input" events even active in the script at that time. you could have a faulty line in an "on input" event in one of your other scripts... the proper command to send a message is /msg $chan $1-
the not registered error is a mystery to me, because i haven't gotten the thing even once. i think once yesterday i saw the error message but it didn't stop anything from working, and it still used the regcookie nickname.
at any rate, there may be *minor* updates to the current ClearMSN file, but I am concentrating on doing a complete revision/rewrite for the next full release, so for the most part bugs that would require a lot of coding to fix will remain unfixed. sorry for any inconvenience, but i think my scripting ability has sort of outgrown the confines of the current file.
in the interest of heading off bug reports for things that will not be fixed until the next full release, i'll post this list of KNOWN BUGS:
> Occasional "Not Registered" Errors in Groups Chat. Just rejoin the room to work around this.
> Complete disconnect from MSN is not always re-connected.
> more to come? I hope not.
