[Dropped] Thumbnails revert to Apache logo

[FENRISULFR]

I have a lot of files especially color coded. I am able to view these as thumbnails, where they show as a miniature version of the open document. But if I change anything and close the document, the thumbnail reverts to the blue and white Apache birds. This doesn't happen in any other files but ones that have tables in them.

Edit: Split from Disable document thumbnails in Windows because your question is different so you need your own topic. Please do not post in another's topic unless you are helping to solve their problem for them.

You haven't mentioned what operating system you use. Perhaps you might take a moment to update your signature with that information.
