About the template box crash:

I cannot seem to reproduce this error in any way. :-(

Is there anyone else that can confirm having this error at all, who might maybe even be able to give me additional hints about how to provoke this into happening?

Bitt, can you tell me exactly which templates are in your drop-down box when this happens? Have you added any of your own, or is it only the two default templates in the box?

Also, you say the following:
"Then I clicked the arrow to select the other one so I could remove it as well, but as soon as my cursor gets to the dropdown part of the dropdown box, I get the error dialog"

With "the dropdown part of the dropdown box", do you mean the list of choices that is dropped down immediately when the arrow has been clicked, or do you mean the text area where the current template is displayed?

This is very strange, because there is no code connected to moving the mouse over that area at all. :-(
