Originally, during testing, the improper behavior occurred only  
occasionally, which led to that decision.

With 'remove duplicates' cleared, duplicates *at the bottom* are  
written to the history list/file but filtered out when the history  
file is loaded the next time R.app is started.

Setting 'remove duplicates' removes *all previous* duplicates in the  
history list as you go (to keep useful history as short as possible).

Agreed, it is perfectly ok to out of habit start R.app by d&d-ing a  
file or directory on the icon.

Looks like it. Thanks for your effort.

All thanks there (and the other 99.99%) goes to Simon. I agree, 64 bit  
works really well.
