Well, last night, my mirc.exe file got corrupted somehow. It froze and I closed it and reopened it and it would crash immediately every time. I replaced the exe and it works fine again, so it wasn't a script problem. Anyhow, you know that "send bug report" window that wil usually pop up when it crashes? If you view what's in it and view the tech info (you click two links to get to the info), you'll see the data that would be sent. If you scroll down, you'll see the hex information. Scroll down far enough and watch the ASCII representation of that hex (the right side) and you'll find the reason why it crashed. Of course, you may not be able to figure out what it means... but, it will still give you the reason and it may be useful.
