yes, this might be a short-term option. I'll try to remember to have another 
look, soon, and see, whether it can find a way to fix this, properly.

Yes, indeed. This will need some reworking.

About the commands being executed several times: It happens when submitting a 
construct like this in a line-by-line fashion:
	{
		print (1);
	}; print (2); {
		print (3);
	}
What throws us off is the third line: When submitting the command up to this 
point, the parser tells us the statement is still incomplete, but actually, 
some of it was a complete statement, and has already been executed. It's a bit 
embarassing, but fortunately this is not triggered all too often (and it's 
another reason why Shift + F8 and Shift + F9 run the command a bit 
differently).

I am in the middle of a large rework of the internals of the interface to R. 
This should also make it possible to fix this (but don't hold your breath).

Regards
Thomas
