[R-SIG-Mac] Rgui freezing on function lookup

[Elizabeth Purdom]

Hello,

Lately on my mac OS X (snowleopard) computer, when I run the Rgui it is 
freezing because of its function lookup feature.

Specifically, as I type at the command line, there is a feature where if 
I type "print(" it shows at the bottom the arguments for the print 
function. The problem is when I type a typo (my frequent typo is 
"heaD(") it goes to look this up and completely freezes my Rgui and I 
have to force quit the program. Of course the feature does it as I type, 
so it doesn't matter if I press the backspace to fix it, etc. It's too 
late. I don't remember it doing this before, but now it happens many 
times a day --  I don't know what has changed. It also doesn't do it all 
the time; I think it is related to having set options(error=recover). 
This is because it is producing an error that it can't find heaD as a 
function.

Is there a way to turn off this feature? Failing that, some work around? 
Its not responding to escape/ctrl-c etc.

Thanks,
Elizabeth Purdom
