The only issue I am concerned about is that, as mIRC is single-threaded, write-through/flushed updates to slower, non-SSD drives may freeze the interface every time there is an update.
That might indeed be a problem. Oh well; if it turns out that MoveFileEx() still does not solve the BSOD problems for many users, it could be a next thing to try.
Unfortunately I have no more details about this event.
Alright. Thanks!
