I'm not seeing this issue. What browser and OS are you using?
I recommend upgrade to mojoPortal 18.104.22.168 released today.
Note that we did upgrade to the latest version of FCKeditor, and it was also included in your current build. If the old FCKeditor scripts still exist in your file system you could change this setting to point to the old version.
<add key="FCKeditor:BasePath" value="~/ClientScript/fckeditor265/" />
I think the old version would be:
<add key="FCKeditor:BasePath" value="~/ClientScript/fckeditor264/" />
Make sure the folder /ClientScript/fckeditor264 exists.
Hope it helps,
