jason,

 

Strange. It works just fine here.

Can you try the following configuration?

 

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <contextmenu>
  <item name="Editing" value="False" />
  <item name="Format" value="False" />
  <item name="Insert" value="False" />
  <item name="InsertAdvanced" value="False" />
  <item name="InsertFiles" value="False" />
  <item name="InsertForms" value="False" />
  <item name="Relative" value="False" />
  <item name="Tags" value="False" />
  <item name="Verbs" value="False" />
 </contextmenu>
 <toolbars>
  <item type="g_start" />
  <item type="table" />
  <item type="image" name="Save" postback="True" />
  <item type="image" name="Bold" />
  <item type="image" name="Italic" />
  <item type="image" name="Underline" imagename="under" />
  <item type="separator" />
  <item type="image" name="JustifyLeft" imagename="left" />
  <item type="image" name="JustifyCenter" imagename="center" />
  <item type="image" name="JustifyRight" imagename="right" />
  <item type="g_end" />
  <item type="holder" name="insertcustombutonhere" />
 </toolbars>
</configuration>

 

BTW, which version of Cute Editor are you using?
