3D View goes blank, how to "refresh"
The 3D view displayed in a separate window is blank when I switch back to SH3D after using other programs. Is there a simple way of "refreshing" the 3D view when I return to SH3D so the image returns?

How did you install Sweet Home 3D?

Too bad, I thought this bug happens only under Java 7 with Java Web Start.
Please try to resize Sweet Home 3D window or move the separators around the 3D view, it should refresh the 3D view.

Thanks for the suggestion. I tried it already, but it doesn't work.
I usually have to close the 3D view so it displays in the main window and then select Display in separate window again. This often takes about 2 minutes. Sometimes it is so unresponsive that I have the Exist the program and re-launch. Anyway it's not a big problem I just thought there may be a simple solution.

Re: 3D View goes blank, how to "refresh"
I had a very similiar problem: when opening any properties windows for furniture, the 3D view would go blank. I fixed this by killing this 3D view refresh code:
