I have had similar problems with these screens in the past, where the display will freeze and hold on switch functions etc. This problem disappeared when I updated the WIN CE version it was running on. Have you any idea which version you are on?

Hi To extract the software from an OP you need a program called prosave. This will take a copy of the software but you cannot edit it, only download it into another OP. THIS link should show you what to do. BUT, if you plan to replace it with a newer screen, you'll probably need to rewrite the software anyway and possibly think about a different comm setup. The screens are more like pcs now with siemens latest range available HERE. There are still places that will repair your screen, do a bit of googling. I'm told siemens still repair them. HTH

Are you using protool? If so then in the menu goto system-> settings and you will see the password box. As above, default is 100

easier way is to use a dbf editor. SHUT DOWN S7, then browse to your project file e.g. c:\my documents\some s7 project\ombstx\offline\00000001 and within this folder is a file called 'subblk.dbf'. Copy this file onto root i.e c:\. Then place the dbf editor on root c:\ and open a dos prompt. Then type c:\dbf_edit subblk.dbf and this opens the file for editing. Then using the right cursor, scroll along until you see the column 'password'. Then look for instances of the number '3' and replace it using the enter key for a number '0'. Press esc to exit the program and then copy c:\subblk.dbf back to the original place you copied it from. start S7 and open the project, the KNOW_HOW is no more. HTH dbf_edit.zip
