They aren't having the same problem as me, but their check sum is the same, they have patched mIRC's
and.. i just unzipped an old mIRC script, in the theme.mrc i type in 3 random lines of code, then closed mIRC and reopened it, they were there.
if i paste in my new theme code, yet again it deletes it, it's like it's reading the code then deleting it back to a point where it thinks the code is fine.
Don't say it's to do with the mIRC being patched, because it got patched the day 6.31 was released, and i was scripting on it fine, and everything was saving fine. The same as everyone elses mIRC that has been patched that i've just spoken to.
