OK, been going round and round with this one. Looking for ideas here. For whatever reason I am unable to post a link in posts of a favorite online forum I frequent. I click the little add url icon and a window comes up asking for the link. I enter it and click OK, the window disappears but nothing appears in the post. Adding text or pictures, modifying a post, etc, no problem. Every other feature on the forum works for me. Forum Admin thinks it has something to do with Java. However I AM able to post links in other forums. I've also refreshed my Firefox with no improvements. I can go with Explorer (not Edge) and have no trouble posting a link which suggests it has nothing to do with any other aspect of my machine. OS is Win 10 current version. Firefox is also current version. Web site involved is: https://www.rcscalebuilder.com/
