I’m having the same problem. Had v2.5 and upgraded to 2.6.1 – still having the same trouble. Can’t switch from Visual to HTML without losing all the text…clicking Save or Publish gives me a notice asking if I’d like to continue because all changes will be lost. This is from Firefox
Just tried it in IE – that seems to work.
But during the post process I get this error:
Error in my_thread_global_end(): 1 threads didn’t exit…and updating my settings hasn’t helped so far which means I’m on the lookout for another fix. Hopefully it will solve the issue with posting also!
