Still having problems with missing images in Viewer Display

At this point I'm just reporting the problems showing up in the Viewer.  I have an application more or less running but every time I come back to work on the Project (Hide_and_Seek_v0305) the View of the Project shows a different set of missing (blank) images.  All of the "missing" images are Button Images and all of the actual images appear to still be part of the Project.  Sometimes I can get the images to re-appear by just changing the image to a different one and then changing it back to the correct one.  Other times I can do this many times and have it never appear.

This problem just started showing-up yesterday.  Before that the displayed images always seemed to be stable.

If there is something I can do differently to work around the problem I'm cool with that.

Thanks,
