Hi Jan,

Thanks for the suggestion.

Another possibility is to remove the Platform SDK menu option and to 
always enable the Platform SDK. I think that menu option was much more 
relevant 20 years ago than it is today since 20 years ago the Platform 
SDK was a separate download. That's no longer the case today.

Thanks,

Bart.
