I've been using wordpress on my server for about 4 months now, and it was great at first, however I've noticed numerous problems as time went by.
1. I cannot click & drag my widgets. I click them, and nothing happens. There has been 3 versions of wordpress out since I've noticed this error, and the issue is STILL not fixed, even AFTER I posted a separate topic the day the problem began
2. In comments, I am able to approve, etc, but once I do a quick edit and submit the revised comment, it will not allow me to re-quick edit another post, NOR will it allow me to approve, etc, unless I refresh the page.
Those are the only things I can think of as of now, but I'm sure there are more issues.
