sync malfunction

Hi,

can anyone confirm this experience?

Sync 2 local folders:

folder 1 (PC) - empty
folder 2 (USB-harddrive) - empty

1) Generate a file (e.g. "test.txt") on the desktop and move it to folder 1 - file appears in folder 2.
2) Move file from folder 1 back to desktop- file will be deleted folder 2.
3) Move file again from desktop to folder 1 - file will be deleted in folder 1.

I tried this procedure several times starting with folder 1 as well as folder 2 - the result is always the same bad thing - folder 1 and 2 and desktop are empty - test-file is gone...

WIN Vista 64-Bit
TIH2012 latest build installed

Thanks,
