TimyMCE display and editing problem when edit Ads
I got some display problems with TimyMCE when someone EDIT an Ads :
1) Part of text covered by gray spot are so can not be seen
2) The editing are wider than it should be.
I attach the screen capture here.
Beside that, I want to prevent user from input external link using TimyMCE editor by disabling or hide the icons.
Hope someone can help me
