Forums Connection Issues mIRC has encountered a problem and needs to close.

I use mIRC on three different Windows XP Pro installations myself, all on different computers, all of which have full patches applied from the Windows Update website, and I have not experienced this problem.

It's difficult to guess where the problem might be since you're reporting that the crash happens in Winsock itself. It may simply be due to a conflict of some kind with your software/hardware combination.
