I am experiencing a problem with the List View control.  I have managed to 
isolate the problem to machines with different versions of mscomctl.ocx.  
The ones that work have version 6.0.88.62 (22/05/2000)  which came with 
sp4, the version that doesn't work is 6.1.83.41 (07/12/1998).  I have 
looked in Microsoft's DLL database, and this version is not listed.  Does 
anybody know where it comes from.
