I am having what appears to be a related problem, i.e., external link WITH AN ANCHOR is not working.
For example, using this url: http://www.urantia.nyc/en/Xrfdhtm/003.htm#3_1
If you cut/paste this url above into a browser nav pane it works fine.
HOWEVER, when used within a Jevelin TEXT BLOCK, it fails. See example here: example
You will notice that:
Please advise at your earliest opportunity. I need to know whether or not to abandon my plans for Jevelin.
