This is an apparent bug in Commander version 4.2.16 that seems to be related to a configuration issue. To reset the sizing and correct the issue:
1) Close Commander
2) In Window explorer search for SglLoop.txt (It will be in the directory that Commander was installed -- Normally: c:Program FilesCommander 4.2SglLoop.txt)
3) Delete SglLoop.txt file
4) Restart Commander... The single loop display should now display as expected.
This problem has been corrected in Commander 4.2.17.
