GnuCash and date picker

Hello all,

does anybody have an idea what might be wrong with date picker in GnuCash? It is locked and only current date can be recorded. I used GnuCash earlier and never had such problem. :\ (Now I have version 2.2.8, with Czech localization, and OpenSUSE 11.0). What a surprise when I logged as root and use English version this problem did not appear. :sarcastic: I tried to create another user account and started GnuCash, but the problem persists.

Thank you in advance for any suggestion.
