Dopus Viewer opens floating Word toolbars

When you highlight a Word file it opens in the viewer as well as two floating toolbars which are actually add-ons (circled in red in the image below).

The toolbars can be closed by clicking on the "X". However, if you select another Word document when it shows up in the viewer the toolbars pop up again. This is extremely annoying behaviour that renders the viewer too awkward to use.

By the way, when you open Word normally these toolbars are in the regual place - NOT floating as with the Dopus Viewer.

Our software is:

Dopus 9.1.0.6.3044 x86 with ActiveX + Preview + Office + Web version 3.1.0.5
MS Word 2003 11.8215.8202 SP3.

How can we have Word open in the viewer without these floting toolbars?
