Most Recently Used Documents fills up with DST files
Starting with AutoCAD 2009, the most recently used files list is designed to list both DWG and DST files. Unfortunately, once nine (cumulative) DST files have been opened by one user, then the most recently used documents list will no longer contain drawing files.
Workarounds:
I wrote this command to completely reset the MRUF list. This will remove all entries from the list. Over time, be prepared for it to be populated by nine DST files again. When that happens and it gets to be too annoying, simply re-run the command. (Note: I’ll add the LSP file to the downloads section ASAP.)

;;This utility can be used to clean out the mess that 2009 and 2009v2 leaves in
;;the Most Recently Used Document list after opening nine or more DST files
;;absolutely no warranty
;;feel free to modify as necessary
;;I use this only periodically. I run it manually when my Recently Used Files list gets filled up with DST files.
