The Properties window (brought up via right clicking an item in Thunar and clicking Properties) no longer remembers its size and defaults to a rather unwieldy one. This is occurring under Xfce 4.12 on Xubuntu 14.04. Thunar version is 1.6.6.
It has never remembered its size, but it has been increased from 400x430px to 500x550px per default because with some translations the text was always ellipsized, which is not good.
This is by design. Closing.
was not aware of this guys. thanks for the clarification.
