advdbgrid column size


i've TMS Component Pack and if i add a new column on a grid (with columnsize all false) other exsisting column change width size !!! I must again to resize manually the columns !!!
There is anyway to FIX or block the size of columns witdh ??
Thank u. 

I retested this here with the latest version and cannot reproduce a problem. Adding a column does not affect the size of existing columns.

How exactly can this be reproduced? You do not mention whether you add the column at designtime or runtime, how you add it , etc...
