If F1 does not open online Help and/or Shift+F1 activate the "What's This Help" button either, please read this thread. Try xberk's suggestion first. The VMS16P help file is MovieStudio160.chm in C:\Program Files (x86)\Sony\Shared Plug-Ins\Help Files. Instead of \Sony\ it may be \VEGAS\ as mentioned in that thread.
(And please create a new thread for the questions not related to the topic, so interested users will be more likely to find them.)
Go to Options/Preferences but hold down Shift as you click on preferences. In the Internal tab type in Legacy at the bottom to get the items. There's several. Change FALSE to TRUE for the ones you want. I've activated both Stabilizer and Titler as you can see.
in version 17 can you run a good old image stabilizer?
