Version: (using KDE KDE 3.5.3) KPPP contains a lot of long strings, in which lines are broken using "\n" character. This causes problems when resizing windows. Example: "Finished!\n \n A new account has been created. Click \"Finish\" to\n go back to the setup dialog. If you want to\n check the settings of the newly created account,\n you can use \"Edit\" in the setup dialog." These strings should be transformed into Qt rich text (<qt><p>Paragraph 1</p><p>Paragraph 2</p></qt>) and maybe different widgets used (with layouts), so that dialogs can be resized properly.
This project is unfortunately no longer maintained. If a new maintainer wants to step up and take care, the project is archived here: https://invent.kde.org/unmaintained/kppp You can just clone it in your private namespace on invent.kde.org and if you have started to work on it and fixed/implemented something get it reviewed and the project unarchived. Sorry for the inconveniences.
