For what it is worth … I had a similar problem recently. I could not render to any “single image format” (i.e. jpeg, png). This was true even when using the software renderer. I re-installed the latest software patch (#3041) and the problem was resolved. The cause of the issue was unknown, but I chalk it up to Vista.

Hi Alan,

Yes, you were correct. Under OpenGL hardware acceleration, several strange things have happened. If I resized the main window, I could lose the stage (back to gray). By resizing again, the stage would return to it’s normal display mode. Further, even when the stage was operating correctly, I could not select an emitter without zooming in quite substantially. When software rendering was turned on everything functioned as expected. I will attempt to upgrade the video drivers. Strange, however that this laptop is less than a year old. I would not have expected driver problems so early on.

Thanks again for setting me in the right direction.
