Thanks for the hint Fernando,
Unfortunately, Sysinternals sees the *.vc? files used exactly the same whether VFP simply set classlib to *.vcx or 'locks' the DTE class in memory as explained in my earlier response to Rick.
>@Thierry: With Sysinternals Process Explorer you can find which VFP session is using this VCX (just search with the library name)
