Vito, All I can suggest is that you keep trying. I did a few tests after reading your post and found that Agent (but not Quicken) had reverted to US format. When I checked win.ini I found it had somehow been overwritten with the US format. Don't ask me how! I amended the line in win.ini and everything is fine again. What we need is a developer to explain why the line gets overwritten. BTW I am using wine 0.9.59 .
