Using Instant Text with Windows 7

I just installed Windows 7 Home Premium and am using Instant Text with Office 2003 as I have done in the past with no problem.

However, suddenly, I can't get Instant Text to stay linked with my Word document. Also, when I try to link Instant Text, my Word document shrinks to just a few lines, and I can't get it back to normal size with IT running.

Any suggestions?
