Our current site sits on Drupal 7 with all updated core and modules. The theme it resides on, Solaris, requires its wysisyg to be fine tuned as its not providing properly functionality.
The other tweak we need is to have the realname module (already installed) to display the full name - first and last - when a user adds a comment.
Hi, I've worked with both the WYSIWYG and Realname modules in past Drupal projects, and hopefully can be given the opportunity to help you with the issues you are having. Thanks!
