When you launch a floating dialog in 3ds Max such as the Material Editor or the Render Panel you may wonder where it is and how to bring it back.
This usually happens when you changed your Desktop Resolution and re-launched 3ds max.
What causes this problem?
The root of the problem comes from the fact that last used dialog positions are stored in the 3dsmax.ini file. Unfortunately, none of theses dialog are coded in a way that they check if they are restored in a visible portion of the desktop, resulting in many cases as “out of reach” locations.
How to resolve the issue?
Until this bug get resolved in 3ds Max directly, there is a neat little utility that you can use to bring back “missing dialogs” in the visible portion of your screen: SnapWindows. Just run it while running 3ds Max to reset the location of floating dialogs.
