Location of user setting file

Dear Developer,

Has Avogadro under Windows OS any hidden files with user settings data?
For example, where the “Open Recent” file list or the last molecular
graphics settings are kept.
It happens a very strange behavior with my Avogadro program. If I try to
open an XYZ coordinates file for the second time the program frozen and
after a while crash.
I thought, that if I remove the user settings data, maybe I could solve
the problem.

Thanks in advance for your help
