I did try and got the following message:
The module "c:\support\slide.ocx" was loaded but the call to DllRegisterServer failed with the error code 0x80040200I don't know if this is due to the ocx not being compatible or whether it is due to the registration process in Vista - it seems you need to allow implicit permission to do absolutely anything with security dialogs poppping up if you simply want to rename a shortcut
If anybody has used it and it works then I'll know to keep plugging away at it.
