>Don't write to registry. Use INI file instead.
This is what I have been doing for years. But, in this particular situation, it was voted to write in it.
>Craig B recently gave me a link to a really good document about Windows 7 compliance. The simple way will be to forget about registry and use INI files - that's the Windows 7 standard. I recently converted one of our apps (in VFP) from using registry to using INI.
It might well end up into continuing to use the INI approach on that application if we cannot find the reason of all this.
