Attempting to drag widgets in http://tarverator.wordpress.com/wp-admin/widgets.php#available-widgets usually simply selects text. Sometimes, if I fiddle with it, I can get the widget to look like it is dragging, but it won't "drop". Also, the page won't scroll up when I take the Text widget, which is what I want to add to my sidebar, and hold it against the top of the page.
The problem occurs in both Chrome and Firefox on Linux Mint Mate Maya.
Most of the help I have turned up for the problem of widgets failing to drag to the sidebar suggests "turning off the plugins" but my wordpress.com blog doesn't have any plugins, so far as I can tell.
Suggestions appreciated, thank you.
The blog I need help with is tarverator.wordpress.com.
