I keep running into this problem when reading and writing from and to a file excessively, eventually when deleting a line from it, mIRC will return "cannot open file" yet it will still write to the file. Restarting mIRC does the trick, but I was hoping for a solution that doesn't including restarting mIRC all the time (or changing the fact that i want to write/read from a file). I'm using mIRC 6.12. A fix in the next version would be cool, thanks smile
