One more stupid question if I may

Got to File/Make... and make the OCX.
Save the project.
Close the IDE.
Copy the *.OCX that you generated to the folder cmp
Rename it as *.cmp
Open the project in the IDE.
Go to Project/Properties, and in the Components tab, in Binary compatibility select the file *.cmp in the folder cmp.
Click OK.
Save the project.

I assume by that 2nd instance of "project", you mean the one you want to use the new SSTabEx in, correct?
