Sorry for being so late coming back on this, I was travelling the 
weekend. I tried to remove as much as possible from the workspace 
(.RData file), but nothing created by Rcmdr. This did'nt change 

Then I downloaded the latest Rcmdr (0.9-0, development version) from 
John Fox page, and compiled it myself for windows. The focus problem 
is unchanged, but now the problems with attaching a dataset has gone, 
the warnings about _ being deprecated has gone, happily. 

Also, the problem with printing the .logFont variable seems to have 
gone. In all but one trials it did'nt bomb Rgui.
