There appears to be a bug in CSM version 4.3.1 where CSM4.3.0 works fine.

If small icons picked on first column, and large icons picked for second column,
most icons on second column show incorrect white file icons.

The only way to get them to refresh properly is;

Set both column icons to large size, 
click the start button to bring up menu,
then set first column to small icons, click start menu button.


Drawback is if computer, or Classic Shell restarted,
one gets the same problem again.
