DS Free Custom Paper Size

Hello

I am working on Windows 10 x64 home and DS 2018 SP3 x64

I notice that the custom paper size for a PDF output is kept in a .cfg file and in the memory.

If you close the file and then open it again, no problem, everything is OK.

On the other hand, if you close the DS session and then open it again, big problem!

The custom configuration is not read by DS and the paper size is changed to that of the default configuration.

As a result, the custom paper format must be recreated.

Do you have the same problem and how did you solve it?

Thanks in advance  JP
