If you want to change your default transfer settings, go to preferences:

Well thank you very much!

When you select the option to 'use same option next time' in the Synchronize dialog it will not take into consideration the changes you made to the transfer settings. I am trying to sync ASCII files (Windows on one side, Linux on the other) and I have to change the transfer settings every time I sync. I think the transfer settings should also be saved in the options for next time.
