I foolishly updated to the 'new improved' Texstudios, after having used the old one happily for a few years. This version stinks. 1) I cannot edit a file, update it, and recompile. TexStudio keeps recompiling the OLD version , and I don't tkhow where the old version is even saved. 2) I cannot get TexStudio to recognize Sumatra, through which I want to veiw the resulting .pdf file. I have to do this by hand. WHY CAN'T YOU PEOPLE LEAVE WELL ENOUGH ALONE?
