R help - Apr 2006 - R GUI for R2.3 hangs

Hello,
	I recently installed R 2.3 for Tiger 10.4.6. Though the commandline  
R works (i.e R at the Terminal), the R GUI hangs while trying to load R.
	Once it did run, and gave many errors regarding Quicktime and DivX  
libraries.
	Is there anything I can do?
	
	R 2.2 however works fine.

	Thanks
	Saptarshi
