Solved Movie Studio Platinum 12: Video FX window won't open

I can select the first Video FX that I want to use, and the little FX button then turns green, but the Video FX dialog does not display. It doesn't matter how I try to open it (right-clicking in the clip and selecting Video Event FX... from the pop-up menu, or using keyboard shortcuts.... NOTHING happens.

I've tried restarting Movie Studio with the resetting of All Defaults, but same result.

Hi Pixel Smithy

The program is not broken, your Video Event FX window has either slid off the desktop or is docked into the tabbed window area.
I can't see all of your desktop, so I don't know which option applies to you.

If you have accidentally docked the Video Event FX window, it will be located here.
Grab hold of the handle "row of vertical dots" and drag back onto the timeline.



If the Video Event FX window has slid of the desktop, it will be hiding underneath your Windows Taskbar.
Right-click Taskbar and select Properties.
Turn ON Auto-hide Taskbar - apply & OK.
If you can see window, drag it back up. Once done, you can reset the Taskbar back to staying on.

If you have TWO monitors connected, make sure to turn on Monitor No.2 and see if anything is hiding there.

Lastly, you can do a full reset of the program which will default all settings and clean the Vegas Cache.
Do this:
Turn Movie Studio/Vegas Off.
Hold down CONTROL and SHIFT keys at the same time AND ALSO AT THE SAME TIME double click program icon on Desktop to Boot program.
Window will pop up.
Select Delete Cache and Yes.
This will restore program to Factory Default Settings.
