Dears Tinn-R users, Before 2.15.0 the caption of 32 bit was only "R Console" and now it is "R Console (32-bit)". In this way Tinn-R is not recognizing Rgui 32 bit, due the caption is used for it. ( I have been receiving emails about it from the users). So, my suggestion to workaround is (inside of Tinn-R): Options/Application/Rgui/Recognition - Type (caption search)* set Partial (by default Whole is set). In few days a new versions of Tinn-R will be released fixing this feature. All the best, -- ///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\ Jose Claudio Faria Estatistica UESC/DCET/Brasil joseclaudio.faria at gmail.com ///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\
