1.It would need some wrapping for filename if too long
2.More importantly it should scale if made larger

If you read the post for the mirc beta on the website, it told eveyone to reply on the bugs forum for the beta. While you post may be seen in this forum also, its posted to the wrong forum.

This is not a bug report, it's a feature suggestion. There's no reason to believe the current behaviour is anything but intentional, though I'd personally consider the lack of scaling a little on the fence.

There's nothing wrong with reporting feature suggestions in the feature suggestion forum, even for features specific to the beta.

Yep. Very annoying. It should behave as before.
