Can't create a new Design Table

SW2010SP2.0 (with both hotfixes), Win 7 x64, Microsoft Office 2007 SP1

I can no longer create a new Design Table. All the button clicks are there, the Design Table Property Manager has all the usual options (Blank, Auto-create, etc.)....

....but, when I click "OK".....nuttin' happens.

I can still edit open existing DTs - just can't make new ones.

The SolidWorks user next door, with 2010SP1.0 x64, can create new DTs just fine.

I've already submitted an Rx to my VAR, I just wanted to see if anyone else is seeing the same thing.....or if it's just lil' ol' me.....

Thanks!

Steve
