Important instructions for windows users for making the menus work well
The most important technical point about this menu and the R-Commander in general:
The R GUI should be installed with the Single Document Interface (SDI) mode instead of the default MDI mode. John Fox, the author of R-Commander, has described how to change MDI to SDI, if R has been installed in the wrong mode (http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-notes.html). It is strongly discouraged to run the R-Commander under the MDI mode, as it happens very frequently that windows suddenly disappear. They usually have iconized only and can be retrieved from the taskbar; nevertheless, this behavior can be very annoying and can be avoided by using R in SDI mode.
