The problem you are having ususally happens when a project that was created in the 1.0 or 1,1 versions of NevoStudio is uploaded from the NevoSL back into NevoStudio
Because Windows CE substantially enlarges image files when they are converted from WindowsXP, when they are uploaded back into the PC (and Windows XP) the images files are merged into the backgrounds in the Nevo projects.

The fix is twofold:
1. On Home pages, and other pages where you have custom' buttons, you will want to drag a copy of those buttons and drop them on top the ones already existing on the page. The once you are done with that, you can drag a copy of the background from the background gallery and drop it on the page. This will totally "fix" the page.
2. On pages in a devce page collectio that were created using the 'Add Device Wizard" - just drag a "theme" from the Theme gallery over the whole Page collection and drop it. This automatically fixes both the buttons and background.

This issue is not a probem, if you are uploading a project from a NevoSL that has either the 1.2 or 2.0 version software - into NevoStudio 2.0
Hope this helps!
