Hi
1) Make sure PADS Layout is closed.
2) Locate the powerpcb.ini file. It is default placed in C:\MentorGraphics\PADSVX.1.2\SDD_HOME\Programs\
3) Open powerpcb.ini file in a text editor.
4) In the [dialogs] section - look for 'Display Colors Setup - Position='
5) Delete the entire line and - save the .ini file - close the text editor.
6) Open PADS Layout. Now the Display Colors Setup dialog will be placed in a default position in the middle of the screen.
Hope this helps.
regards Klaus
