Consider a two form app. An mdiparent and mdichild. The mdichild mousewheel functions work fine in the mdichild until I click on a mdiparent panel's radiobutton and focus is transferred to a control on the parent.

I am unable to redirect focus from that mdiparent panel's radiobutton back to my mdichild form so that my mousewheel will once again be operational. I've tried activateform, activate, activatemdichild,.focus,.capture,
and just about everything I can think of, apparently except the right thing.

Your help is appreciated. I think my problem must be simple but I am stumped. I can't seem to find a reference anywhere on how to make this work and I have referenced 7 books on vb.net 2003. What am I missing here? Thanks in advance.

Mike
