Hello! I and my friend have the latest R version (2.12.1). She has a Dell laptop and I have a Dell desktop. Both of us have problems with using "Ctrl+r" when we are trying to run in a selection in R (regular R script). Sometimes it runs, but frequently it does not run at all, so that one has to higlight the code again and run it again. I also have R on an HP laptop and I never have the same problem on it. Has anyone encountered thisproblem on Dell machines? Any advice on how to fix it? Thank you very much! -- Dimitri Liakhovitski Ninah Consulting www.ninah.com
