Office 2007 documents not opening immediately...

Hi, I use Office 2007, and I have an issue with opening documents. It doesn't
seem to matter which program within Office I use (usually Word or Excel), but
for this example, I'll use Word.

If I already have a Word document open on my PC and then open another one
(by double-clicking on it in a folder, not opening it from within Word), it
doesn't open right up in front of me. Instead, the previously-opened document
flashes blue on the taskbar and I have to click on it in order for the
newly-opened document to come up.

Is there an option somewhere to get rid of this "feature" and just have the
newly-opened document pop right up?

Thanks!
