Does native comctl32 help? If it does I think I know where this slowdown comes
from (we might have a report for that in comctl32 section). When you select a
new file it probably sorts whole list again and again to update selection for
example. Some years ago selection handling was broken - it wasn't properly
updated when you sort a list, I fixed selection and it's probably a reason.
