Coreldraw 12 file open window stuck in date modified order

[Dragon427]

open window is stuck in date modified order, you can change to detail view and chick on the name column header to change but if you go to another folder or return to the same folder it is in date modified order also if you take the date modified field out in the field box when you return to any folder it is back and in date modified order, windows explore is fine all alphabetic and retains folder option only coreldraw 12 is effected. I've tried corel help, faq and tools, option no place to find fix
