[R-SIG-Mac] .Rhistory problems

This is the problem that if the workspace is saved, R (R itself, not R.app) also saves a history file, typically with the name .Rhistory. This file is empty and overwrites an R.app history file with the same name. I suggest to change the R.app history filename (in Startup preferences) to something like .Rosxhistory or Rosxhistory or ~/Rosxhistory).
