Hi David,

please try to do a global validation for the window EDITRTWEB.
I don't know if it helps, but it should be worth a try.
In similar cases in PU9 and V11 the script editor presented the code in one line.
After the global validation of EDITRTWEB  it works again as expected.

Kind regards,

 Markus Huber thank you very much. i had been tried the method what your said.

but it's ineffective.

now i edited script in Eclipse. i think , perhaps i changed some cyrause page style....

davidy I suspect you have set the parameter AECLIPSE to YES for your user. So when you try and open the editor it is trying to launch eclipse but is unable to do it. Change the parameter to No and you will be able to open the source in your browser. (Parameter is set in Setup > Users > Parameters> SUP (Supervisor) and the Group DEV (Development))
