I'm so making a necklace out of Ctrl-Alt-Delete.

By adding a property you broke the "contract" between the OCX and it's clients. Forcing the break compatibility is the only way (AFAIK) to get around it without supplying another interface. You will probably also have to rebuild any project that uses the OCX

:omg: well now I feel suitably daft, this is ancient history. Thank you :-D

I suppose it all depends on how much crap you install and/or don't uninstall. I just retired a Celeron 900 system that had run the same install of Windows XP for about seven years. It was a solid, though slow, extremely noisy and huge, system. (At a company I worked on in 2002, we discovered that an NT4 server had been running for over three years without a problem. The funny part was that IT would constantly go on tirades about how unstable NT/W2K was. Seems to me that systems are only as unstable as the people tinkering with them.)
