Now that WIndows XP x64 is out, is it in the future of Mirc for a 64 bit version?

Always clouded, the future is.

Please use the search function first, to see if there aren't any threads that already asked the same thing.

I wouldn't say mIRC 64 will be out any time soon, but I'm
betting the next major version will be rid of all remaining
16 bit code. With that gone, mIRC 32 should run fine on
XP 64. The key word being should.

Behold, a sticky thread named 'Windows XP 64-bit Edition'.

Some have reported mIRC 6.16 running fine on XP64 by the way...
