Hi, I discover that when I save a workspace containing a genefilter (pkg from Bioconductor) object I cannot open no more after. I have to restore the .RData file from a backup to be able to start R again. I didn't upgrade to Version 2.2 but I'm not sure that it will solve the problem.

Hi, I am using R 2.2.0 on Mac OS X 10.3.9. But I test the issue also with R 2.2.1 on OS X 10.4 (Tiger) I have a question regarding the functioning of the history from the command line.
