Take a look at the debug console after the failing operation by right clicking on the Dropzone dock icon, clicking Preferences... and then hit Command+Shift+D.

Paste any output here and I should be able to figure out the issue.

The move is going to an external network drive (Drobo FS). I never had a problem in the last build. When I dragged a file to the folder, it would show the move window, then I would get a blue transfer status bar that updated, then the transfer window would disappear.

Now I get the transfer window, that blue transfer status never updates, the sound of the completed transfer will happen, but the transfer window stays there until I hit the "X" in the upper right corner. The moving of the file does work.

I've tried deleting all my folders in Dropzone and re-adding them. I've rebooted. I've tried quitting Dropzone and restarting it. Nothing helps.
