I was trying to make a video tutorial on using my SMD Collision Mesh Tool for 3ds Max 2010 when I encountered a very annoying bug. Whenever I was trying to bring up the quad menus by right-clicking the viewport, the menu repeatedly flickered and disappeared. Sometimes menu items would reappear when mousing down the area where the menu should have been... but just as often they did not. The disappearance of the menu seemed to coincide with the flickering of the recording marks in my screen capture software (Camtasia Studio).

A thread on Autodesk's Area led me to believe that the issue was a problem with my video settings or display driver. But after playing with all the nVidia settings that could possibly be used, and making sure the drivers were up-to-date, I looked elsewhere. But I could find no answers online.

I finally found the solution... sort of. In the Camtasia record menu, click Tools > Options and go to the Capture tab. Make sure to check the following two options: 

1. Hide capture rectangle.
2. Capture Layered Windows

Checking those options solved my issue for the most part. After posting this article, I received emails from the Techsmith (Camtasia developers) tech support team; they confirm these two settings.

After having made this discovery... I found that it still flickered sometimes. Also, I have received emails from others; this solution is not working in all situations. For some people this works... but some people are still having this problem even in situations where Camtasia isn't running (a display problem between Max and a video card driver is making the quad menus disappear at all times).
