Hi there,
I leave my machine running over night, and I also leave mIRC running.
Recently more often that not I return to my machine in the morning to discover that mIRC has returned a runtime error of: "Runtime error 203 at [hexcode]" or "Runtime error 216 at [hexcode]"
For Example:

When I click okay, the box goes away, and mIRC spews all the msgs and logs it has queued up for the past few hours between when the message came up and when I clicked okay on it. mIRC does not crash.
What is likely to be the problem, and why do I keep getting this error, how do I fix it?
