After running SciTE for a long time on a log file that updates very often. I find that the memory usage gets VERY high. We are talking over 1GB of VM Memory being used, which of course makes the page file very large and massively affect PC performance.
I found this problem is version 1.71, I don't know if it has been addressed yet or not. I have downloaded the latest version and will report back if the problem is still there, please let me know if it has been fixed already.
