Mozilla Thunderbird - 64 bit with KDE - NO RADIO BUTTONS in Setttings Menus

SuSE version of Mozilla Thunderbird, 64-bit, looks OK in general. No radio buttons appear in the Settings choices. Sometimes the actual choices appear and can be selected. Wondered if a needed graphics package is missing for proper display of buttons in KDE?

Thank you,

You choose OTHER VERSION from the menu to indicate that you run a not supported version of openSUSE. But forgot completely to tell what version you use.

Specially when you run an unsupported version it is very helpful to your potential helpers to inform them about such things. Then they can try to recall how things were in those times.

I am not noticing any problems here.

Can you give an example of what is missing?
