Requirements model: Export as Word Document
Using PD 15.3 on Windows 7 with Word 2010.
I just started dabbling with requirements models. When I go to Tools->Export as Word Document, nothing happens. Then, when I go back to the Tools menu, the "Export as Word Document" option has completely disappeared from the menu. If I exit PD and restart, the menu item comes back, but then disappears when I try to use it again.
I checked the Help and followed all of the instructions, ensuring that the MS Word Import Add-In is checked.
Any ideas as to what is causing this behavior?
