I couldn't duplicate what you're seeing on my machine, but I wouldn't  
be surprised if there was some bad data in the defaults database.

To look at the defaults database, run one of the following two commands:

defaults read "com.clozure.Clozure CL" (if you launch via a double- 
clickable app)
defaults read "com.clozure.temp bundle" (if you start the IDE via  
(require 'cocoa))

I'd look for a suspicious entry for "NSTableView Columns  
NSNavOutlineColumnSettings.v1" or something like that.  "NSNav" is the  
substring to look for.  (The system saves the order of the columns,  
the sort order of the columns, and other stuff like that in the  
defaults database.  I'm guessing this information got screwed up  
somehow.)  If you see something weird, delete it with a command like:

defaults delete  "com.clozure.Clozure CL" "NSTableView Columns  

If you don't care to go spelunking in the defaults database, and don't  
care about your preferences, you could just blow away (or move aside,  
at least) your preferences file.  It'd be stored in "~/Library/ 
Preferences/com.clozure.Clozure CL.plst"
