Thanks for your bug report. I would really need to find a method of reproducing this, as I have not experienced this issue myself and no one else has reported it so far. Which version of mIRC were you using before that did not crash?
If you install a clean copy of mIRC into a new, empty folder in your Windows Documents folder, using the portable option in the installer, do you see the same issue?
If you add mIRC to your exceptions list in your anti-virus software, do you see the same issue?
