I hate Microsoft bashing. I really do, but I’m on the verge of breaking my desktop apart with a baseball bat. Well, except that’s too much of a cliché. And we don’t play baseball in Israel. And I would probably hurt myself more than my computer. But still. Very annoyed.
Again, workplace conventions are that documentations are in Word. I'm actually due to start developing on a Linux VM, but some of the documentation will still be in Word (not happy about it as you can tell). I never use Word if I can avoid it.
Right-click on the launch shortcut and add /n after the path. This will open each instance of Word in a separate process and modal dialogs will not affect the other documents. the downsides of this approach are (1) you will need to launch Word another instance of Word instead of use the File > Open from the toolbar/ribbon and (2) Word launches empty (i.e., no default document ready to type in).
not so sure why are there people who are using ms word in 2012, yet, I am glad I came about as I just discovered lyx and the sudo apt-get install lyx I Just typed have made my day ;-)
