I've certainly not seen anything like that and it's hard to guess from your image. Perhaps you can upload a model in which it is happening, this way someone can look at it and confirm one way or the other if it is your system or something in the model that is repeatable for others.

Hi: I think this is right: When you create a new template based on an existing one, you will notice in the style large image a circular arrow imposed over the image. Click on the image, as the arrow represents that you must update in order for it to save.

Text inserted into LayOut in a text box or as an RTF file is vector graphics. There is no option to convert it to Raster. You'll notice that the choices for Vector, Raster and Hybrid are found in the SketchUp inspector. These settings are specifically in the SketchUp inspector because they are controls for the SketchUp viewports only.

Hi Stuart, This may be of some interest to you as well: http://sketchucation.com/resources/tutorials/36-intermediate/115-internal-external-components#redefining-thumbnails (Read the previous explanations too if it is too "brief").

Thanks for responding. I'm a kitchen designer and a very experienced SU user. I use it 4-5 hrs a day for the last 5 years. All that being said, it's working now, 6 hours later. Nothing has changed except the time. I have no idea what is different or what happened. Do you think it could be operating system issue? When this all began,I checked the copy/paste function in a Word doc and it was fine. Anyway, thanks again for trying to help-whatever you did, it worked!
