Automatic ClassID

I create an activeX under VB5 (not VB6 because the ocx container dont support vb6 ocx, go figure).
I note that each time i change the version of the project (in project properties window) then vb generates a new classid for my ocx.

How could i avoid that vb change the classid each time i make a new version ?

by selecting Binary Compatibility unter Project/Properties/Component Tab
