Has anyone noticed this?

in the old mIRC versions, you could go ctrlk24 which, would do a yellow, u would use that, because if u did a ctrlk8 $+ $1- and $1 was 2 or something, it would effectively be ctrlk82

Now, in this new version of mIRC you can't go above 15.. and ctrlk8 $+ $1- where $1 is 2 for eg. still does a ctrlk82..

Anyone else see this, and how can i fix it, and no, i'm not removing the $+
