I read it few times then closed it but now I'm back to this thread...
I think what he means, Hack, is that both OCX and DLL were saved to a project originally, so every time he turns off his computer vbp looses references to either and if you just open vbp again and "re-attach" references without saving it again - it actually "remembers"...
Hmmmmmmmmmmm ... go figure ...

Anyway, I would simply rebuild project by creating a brand new and adding all files one by one including references and save each to a different folder.
