Post problem with Delphi 4 and Informix SE 7.2. ( A = A * 10 )

I have a problem when I try to update or insert values in decimal type fields on an Informix SE 7.2 under OpenServer 5.0.5 All values in a DBGrid, DBNavigator and so on converts themself to the same value "multiplied by" 10 after issuing post, but the insert and/or update work correctly. After post a 2 value converts itself to 22, 3.8 to 38, Where is the bug ? I am using - BDE 5.01, - DELPHI 4.0 (Build 5.37) - INFORMIX driver 3.30 32 Bit. Any help will be appreciated Thanks in advance -- Sergio Dauden Tel: +34 96 337-95-80 Fax: +34 96 337-81-18
