Yes. Exactly.

I am not an expert in the Windows GUI, but as a former user of it, I  
would wonder if my installation of tcltk had gotten corrupted and  
would try to reinstall. Caveat: That advice could be worth what you  
paid for it.

I doubt that would be necessary, assuming the scripts do not have  
function calls that depend on R Commander being around. Files with .r  
extensions are just text files by another name.

I could not find a saveLog function with R-search restricted to  
functions but did find it as an argument to RCmdr. IIRC, RCmdr uses  
Tck/Tl extensively.
