The only change that I can think of that might cause this is item 20 in 6.31
versions.txt file: Fixed $inellipse() bug by enabling floating point consistency option in compiler.
In my tests, this change made mIRC slower by a small amount on the systems that I use. However, it may be that since this method of ensuring floating point consistency is memory intensive, the speed decrease will vary depending on your system compononents.
I implemented this change to ensure that the same issue that affected the $inellipse() routines (a compiler issue) would not affect any other routines in mIRC. However since it has had a significant impact, I will roll it back and apply a fix only to the $inellipse() routine.
