Due to the sheer number of posts on here asking why mIRC suddenly became shareware when the so called "nag screen" was added, I'd say that a lot of people didn't even realise it was shareware before. Now if you ask me it's a good thing that people are now aware they should pay for mIRC, which someone has put their time and effort into building.
If I remember rightly, the screen only disables the "continue" button for a few seconds after your 30 day trial has run out (or when it nearly has). Up until then it's more like a splash screen of sorts with credits written on it, hardly a nag.
I don't see the problem myself..
