I am evaluating Dopus and like what I see.

There is only one issue which seems to be bafflingly unusable.....the desperately slow folder tree. I have searched these forums for clues to fix this and have added dopus.exe as an exception to Microsoft Security Essentials as recommended. But performance is still abysmal, taking up to a minute or more to update (vs seconds for Explorer). GPsoft have clearly invested a huge amount in providing a vast number of outstanding features, yet this fundamental feature seems frustratingly overlooked (or instructions & settings for solving this are).

Is there anything else I can do to make this work snappily like Windows Explorer does?

Many thanks,
