i have installed a ajax load more posts, with previous version of wp and plugin it used to float even when more posts are loaded but with this version it floats only upto posts which are loaded by default and it stops after loading more posts.
This problem is not connected to WP version.
Ajax post loading – is a real problem!
I need somehow to catch an even when you loading more posts and then recalculate widget params… Well, need to think )
You may try older 1.0.3 version – it will not be affected by ajax loading, but it may overlap with the footer
