This may have already been discussed, but when working in PPENG for a while the icons for the buttons, backgrounds, icons disappear. The pixel size is still there but there is no graphic of what the background or button looks like.

If I drag it to a page then the graphic shows up on the page but it not visible in the gallery.

If I close PPENG and open it back up, the gallery displays the graphics fine for a while, then they disappear again.

Any ideas of what is happening? Is this a PPENG programming error?

Thanks in advance.
