Make Messagebox always on top?

What the problem is, is there are documents that users are allowed to edit and then save. these documents are of type .doc and I open them using the microsoft.office.interop reference.

Now when they click the save button in the word application I am catching that event by using the 'wordapplication.DocumentBeforeSave' event.

But when I prompt them the 'Are you sure?' message, it is minimized. But when I bring it up and click ok, the other messageboxes are displaying just fine.

How can I make the messagebox 'z-index', i guess, always on top of the word application?

Thanks,

Justin
