Hi Allen,
Not sure about the toolbar issue, I cannot find a toolbar above the design area. Could you please let me know what version of MacOS you are using? You can find this by clicking on the Apple logo at the top left and selection About this Mac. It will give a name and a version number, ?Also can you let me know what build of PSUD you are using which can be found from Help -> About.
The transformer voltage is set at 240 in a calculator screen, it's not saved anywhere and it just defaults back to the programmed settings every time you access it. I can amend it so it leaves the existing values for when you go into the calculator again during your current session.
Regards,
Duncan
