I have an issue with the latest version 0.218 (svn r8336) compiled with QT 5.15.1. All fields in the Global configuration tab (Tools -> Options -> Tab Emulator/Global configuration) are empty.
see the screenshot here : https://app.box.com/s/lqkuon6wxreudhx1152w7wy84zz2eafn
It looks like a bug : if I type something in a empty field and I push the button Revert to stored values, the correct value displays back.
Any ideas ?
