Problem with the Windows Explorer "outer frame" width

Hi

I have a problem with the "outer frame" of my folders, what I have tried is listed below. Is there anyway to get the outer frame to stay at width I have specified

I have my folder templates set to Documents for each drive & desktop folder
I have set appropriate column widths so can see the widest item in each column including the "outer frame"
I have applied settings to all folders
Have set the disable automatic folder types in registry from another tutorial on this site
Remember each folders view settings is enabled

This result in the folder columns been set for the widest item in each column which is correct.

However when said folder is closed & re-opened the outer frame reverts back to its original size, not what i set.
