Losing icon

[dasymington]

I have a template that I created based on the Text template. It has its own icon but sometimes items based on it change back to the icon for the text template. I haven't been clever enough to see it happen, but I think it's after I've opened the item using Open Document to view it in Wordpad. I've watched as I save the Wordpad document and then click on the Click here to resume internal editing link but it doesn't happen right away.

Any idea how to stop this?
