Client not recognizing updated assemblies on the web server

We have a NTD WinForms app.  Our assemblies reside on our internal web
server.

I am noticing cases where an assembly is rebuilt and copied to the web
server, overwriting the existing one, and the client does not get the
updated assembly in it's download cache (the next time the client app is
started).  In those cases I have to run the gacutil to clear out the
client's download cache.  Then it works.

This does not happen all the time though.  Our assemblies are strong named.
The timestamp does change.  So, why is the client still using the old
assembly in its download cache in some cases?
