Spinning Beach Ball during first sync

[rriccardi]

I just installed FreeFileSync on Mac osx mavericks, and i am in the process of performing my first sync. I have about 16GB of data to sync. I seem to be getting the spinning beach ball every time i view the progress in the program. It also seems to be taking a long time to sync the files, maybe cause of the spinning beach ball? Its hard to view the progress, cause as i mentioned earlier, every time i click on the app i get a spinning beach ball. the time progress seems to jump from 30 mins to several hours. My macbook is connected to my network via an ethernet cable. I am copying the files from a windows server running 2003 server to a 128GB micro sd card in the mac. Is this behavior considered normal? I have a macbook pro retina with an i7, 16GB of RAM and a 256GB SDD. I have 170GB free on my local hard disk.
i hope i will not be experiencing slow syncs in the future with this program.

Can you reproduce this with FreeFileSync 6.13?
