Kmail-trinity account setup problem

G'day List, I'm sure that this has been asked on the list before, but my search-foo is low and I can't find it in the list archives. So here goes ... Trying to setup an account in Kmail-trinity, aptitude show kmail-trinity identifies it as Version: 4:3.5.13-0debian9+r1258263+pr10~squeeze if that helps. Anyway, when I get to <Configure - Kmail>, <Accounts>, <Add> the "Add Account - Kmail" window is too big and the OK/Save box is hidden below the bottom of the screen so nothing that I enter is saved. Moving the panel out of the way does not help on this netbook with 1024x600 resolution and all attempts to resize the window fail. What is the fix/work-around, please? Ta, Glen (stuck in GOF mode)
