I just installed v7.2.0.

Everytime I open the Designer I get an AbstractMethodError.

I am not sure if this is a REAL problem yet or not… just wondered why it was happening.

Updated the ActiveX module and have not seen the error since.

Yes, if you upgrade to 7.2.0 all of the modules must be updated as well since the module SDK has changed a little.
