Can' change comments on column

[Walter Haslbeck <wh(at)hillerzentri(dot)de>]

Hello,

I just discovered another bug (can be reproduced with pgadminIII/rc1 on 
win32 and also with the latest cvs version on linux):

You can't edit comments on columns. When you edit the properties for a 
column and change the comment in the textbox, the 'OK' buttons stays 
grey, you can't commit you change. (It works ok with schema, tables etc, 
 only columns are affected).
