Welcome to the forum.
Dual monitors in use here?
If so, see Snippet 61 on my site
Thanks for welcoming me to the form and providing a solution. I used Rick's method in Snippet 61 and the preview appears.
I'm puzzled why you did it that way. The article starts with a very simple method that does not involve touching the registry but you are the second person to use Rick's earlier method recently. Rick's own view is the first method in the article is easier so what made you use the more complex method?
I really only leave it there in case the first method does not work for someone.
I used his method since the first one didn't work.
When I execuited the key commands and tried to move the window, only the main window moved -- not the preview. I tired a couple more times and them moved to the next solution.
After completing the Regeistry Edit commands, the preview window appeared.
I know this is an old post now but I thought I'd let you know that I've just encoutered the same problem using RoboHelp 8 (as part of Tech Comms Suite 2) and I've had to go into the registry to fix it. The quick fix didn't work.
I may not be the only one who appreciates you keeping a record of all the different options for fixing problems!
Just FYI, I tried the keystrokes on a standalone RH8 and they appear to work (although the Preview window wasn't really lost ). Maybe it's something to do with the Framemaker integration...
