mysterious blank regions - refresh issue?

[innodes]

These are screen captures of a new problem. Some layouts are developing blank regions. They are cleared if you "wipe them" with the debug window or another app window, or if you drag them beyond the FMP borders and then back in, basically effecting a refresh of sorts. Any thoughts or help?

thanks

Shutting down and restarting the computer seems to have helped. I will report if it happens again, or if it becomes a consistant issue.
