I fixed the problem mentioned in my 2nd message. There was a word missing from the DLG_DONTSAVECANCELOK.XML file. I added the word and now the file loads okay in IE. So now all the files re-written the last time I used Poser seem to be fine. The psd's load fine in Pshop; the xml files load fine in IE. But, dang! I still get the error shown in my first message. "runtime/prefs" folder? I'll check there next. But according to TygerCub in the linked thread above, reinstalling created a second set of Poser5 folders and he can't get rid of either one. I can't have that kind of confusion on my hard drive, given my level inexperience, shown by all the problems I'm causing for P5. Hope to hear back from CL soon on the issue, though. I can rewrite the line myself if I knew the proper syntax and which file it is. Thanks for the help! Anyone else, please feel free to chime in.
