Thanks BEKIM BACAJ for reminding me that I wanted to post on this subject! When working with frames and .js files do you find that error messages cite the frameset file, though the line number quoted refers to the actual frame file in which the error has occurred? I find this with NN4.7 in which I do most of my initial development.
