I installed wp-sticky 1.50 and it worked fine for my posts. However, when I activated it my bbpress powered forum disappeared. I all topic threads and posts were not showing. I deactivated the plugin and the forum returned to normal. So it was no big deal but if you are running bbpress don't use this plug-in until they figure out how to make it compatible. I'm not advanced enough to dig into the code and come up with a fix myself.
