Local Files not sorted instantly when changed


since i upgraded to the latest version, on the local file explorer I have files listed by Date Modified. Once i change something on any file , with another program, the file list on local explorer is not updated instantly to reflect the latest changed file, unless i press REFRESH. this was a behavior that I had with previous versions of Smart FTP. So I would expect that if i changed something on a any file and i have sorted by date modified then then last file would be on top, even when i change something with another program.

I hope i described the problem in detail enough.
thanks in advance

here is my system info

It's a known problem with Windows 7. The explorer in Windows itself doesn't always auto support immediately.
