Hi group, I just installed Mathematica 7.0.0 on a Fedora 13 system and everything works fine, except for entering commands. Whenever I type something, Mathematica automatically adds white spaces to the input. For example D[Sin[x],x] becomes D=EF=BF=BF[Sin=EF=BF=BF[x=EF=BF=BF], x=EF=BF=BF] where the =EF=BF=BF only appeared just now when copying it into this .txt - what I see in Mathematica is just a white space, i.e. it looks like D [Sin [x ],x ] and of course this doesn't evaluate. However, it is no problem to manually delete these whitespaces and the input then gets properly processed and the output looks perfectly normal. Is there some way to prevent these whitespaces from actually popping up? Thanks a lot
