After working on several drawings with no problem, today when I opened the next drawing I needed to work on I got the Information prompt, "Unable to load dialog whose id is 4104." After that everything hit the fan. My whole workspace completely changed from the defaults I've had in place for years, text styles changed, the edit text box changed, and all sorts of other things. I've seen other discussion threads on the site that have the "unable to load dialog..." prompt, but I haven't found any solutions from them. I work with Windows XP and Microstation 2004. Thanks!
