Posting here is a good idea but since the ticket has already been made it would draw a lot more (developer) attention if you would signup and add your information in the ticket (posted above).

Preliminary tests show that Version 4.1.4 with guest additions resolve this issue.

Good news and thanks for the update. Does anyone know if the problem that I think may be related to this bug -- affecting Windows 7 64bit guests -- is also resolved? I will be able to test that and report back by 9-Oct-2011.

I am confirming that the new Guest Additions 4.1.4 does indeed fix the freeze problem that I referred to above in a Windows 7 64bit guest. I also confirm that the file drag-and-drop freeze in my WinXP 64bit guest is also resolved.

Yes, works also fine now in my WinXP 64-bit guest.
Thanks for fixing it.

I confirm this.
Thanks a lot.

Great that it is fixed!

I did manage to find a work-around that seemed to fix this issue on earlier versions of VirtualBox (in case there are folks who are unable to upgrade, etc.).

Within your VM
-Right-click on My Computer, select Advanced tab
-Under "Performance" select "Settings"
-Change the setting to "Adjust for Best Performance", and click "Apply"

After doing this the problem went away and I could drag files/folders without freezing up. Must be one of the Visual Effects that trigger the issue but I haven't tried to figure out which one. The setting above simply disables all the Visual Effects.
