Hi!

I don't think this is a bug or a regression; rather, I'm curious if there is some room for improvement here.

When I open history++ gui (by clicking on the view history icon), it takes about 2 seconds to pop up. Not too long obviously but when I check it via process monitor, I see that during this time, miranda has made 81 calls to riched20.dll (I assume this is a rich text editor class library).

I saved the "opening of h++ gui" events via process monitor into a text file and checked it for event counts.

Code: [Select]
root@FortressTL-ArcherC7:/home/vulpix/Temp# awk '{print $4}' grepness.txt  | sort -r | uniq -c
   1296 ReadFile
    162 QueryStandardInformationFile
    162 CreateFileMapping
     81 CreateFile
     81 CloseFile
Each call looks like:

I am curious if this couldn't be optimized somehow. It's a super minor thing and maybe not worth investigating, but it just seemed curious that it behaves this way. Might even be a windows "issue". I'm only relaying what I'm seeing, I don't understand it on a level where I could suggest how to improve it or if there is anything to be improved upon.
