Undesired Copying behaviour
For me I don't want Multiplicity to begin copying on right click on the second machine as it clearly can't know at that point if I really want to copy anything or just right click a folder for it's properties.. If I for example have copied a big amount of data on the prinary and then go to the secondary and right click anything I often had to kill multiplicity on the 2nd as the (undesired) copy process made the machine unresponding. A second bug in my opinion is that it even starts to copy files when I right click something in the right window of Nero Burning ROM, which is clearly undesired.
