(a)  If the program does not respond as expected, hold down <Ctrl> and <Alt> keys and press <Delete>. This should allow you to exit PCMass and start over.

(b)  If your model didn't change as expected, did you remember to save the edited PCMMods.dat file, exit the editor and read in the new model info with <M>?

(c)  *.smm file deleted with file manager reappears. A copy of *.smm is read into PCMass and writen back to disk when the image file is closed. Make sure the file you are trying to delete is not active in PCMass before deleting. Using the "Erase_smm" option in the "File" menu avoids this.

(d)  F10 key may lock the keyboard.
