Hi bradyw,
This is just to rule out before you encounter any problems on IPFS. When designing your InfoPath form, you create these steps:
1. Click File > Design a Form Template
2. Select Blank (or whichever applies to you)
3. Click Enable browser-compatible features only check box
Make sure you were able to check #3.
Then, after form is created:
4. Click Design Checker on task pane
5. Click Change Compatibility Settings link
6. From there, Form options will load. Make sure you enter the correct URL to point to your server's InfoPath Form Services
Thanks,
