Like Uwe, I also get the same message: "Insufficient memory. Please close 
the console." Click the OK button and the console window remains, but 
blank. Start to resize it again and all the text content reappears and R 
seems to be working normally again. This is the same for pager windows and 
in both MDI and SDI mode.

So it doesn't crash now, which is great!
