CODERS/TESTERS! In case of THEME ERROR:
Go into the options dialog and disable the mIRC DeluXe theme, that will disable most of the raw events I added.
Then, in a new script file, use:
raw *:*: { echo -a NUMERIC: $numeric - INFO: $1- }
Every time a raw event will happen it will echo the information into your active window, allowing you decode and test and see if it really is the raw events causing the issue.
Either way, if you turn off the theme in the options dialog (/options) it should stop the issue, if the problem is indeed in the raw events.
