This question may be related to a resolved thread.
After reading the above post, I would like to add some notes to this issue. I am having the same problem with two separate websites. One is build is 1.6.7 (and another) 1.6.8.
The other difference is that I’m not using the List Maker plugin, Instead the areas causing this problem are text areas using the tinyMCE extension. The weblog is also set to automatically make emails and links active.
Site One Email at bottom.
Site Two (email at end of paragraph)
Note: They work perfectly in Firefox, but not IE.
Any thoughts?
