Hello Sky,
I am sorry for the delay of this reply as now is a weekend for us here
1. selected category in word, but post submited selected with default category instead of the selected one.
Regarding the above, I've fixed this issue internally. For the quick fix, download the attached 'xmlrpc.php' and copy this file to folder 'JOOMLA/administrator/components/com_easyblog/includes/xmlrpc/' and replace the existing xmlrpc.php. Remember to backup your original file before you overwrite your existing file with this updated version
2. images in word not added as cover
Regarding the above, I cant seem to able to replicate the issue. I am using MarsEdit as I do not own a MS window system. The image that I posted with MarsEdit did saved as cover photo of my test post. Is this issue only happen only in MS. Word remote publishing? Have you try with Window Live Writter and see if the same issue happen?
3. what this clock means? http://screencast.com/t/Vz1K7DMR
The 'clock' means the post is now under scheduling for publish. Did you configure your window PC the timezone correctly? Most likely you seeing this 'clock' icons means the date time in your pc might not set correctly.
Hope this help and have a nice day!
