Displaying MessageDialog on top of WebGrid

When displaying a MessageDialog in front of WebGrid, I'm unable to click the buttons.

Same behavior when displaying a region with buttons.
Do I miss something ?

thank you.
- Are you using a HTML template? If so, please try to disable the template.
- Has the IWAdvMessageDialog control been placed directly on the form and not on an IWRegion?

If the problem persists, please provide a ready to run sample project that demonstrates the issue so I can further investigate this.
Please also let me know which browser (name/version) and IntraWeb version you are using.

I removed my underlying frame, and all goes fine now.

Thanks
