I have a similar issue on my MacBook Pro, in particular the Drawing Manager palette.
When I click on a header to organize the list by that header, any column widths that I've resized revert to their old widths.
For example, if I click on the Status header to organize all of the drawings by OK, Needs Checking, Embedded, etc. the drawings organize correctly. But if I then stretch the width of a column, like Name or Path, Source View, etc. and click on any header, even if it's the same header, the width of the column I just resized reverts back to the narrower width it was before I made it wider.
Your issues feels like this, I assume it's some sort of bug.
