Upload/Insert Bar Not Working in “Edit” Screen

I’n running wordpress 2.8.5. Until today, I had no issues with it and all plugins worked perfectly. A few hours ago however, while adding new posts, my flash extension (I’m on windows 7 with google chrome) crashed and ever since, my upload/insert bar is not responding. When I click on the buttons there, it is as if I didnt click on anything. The strange thing is, it doesnt happen in the add new post screen, only when I’m trying to edit the existing posts.

I tried to upgrade my flash version, but no help.

I tried to disable the plugins and found out that when Advanced Post2Post Links plugin was deactivated, the issue disappeared. However, the plugin worked perfectly so far and I didnt do any upgrades or anything else, so I’m not sure why the plugin would suddenly mess things up. Anyway, I hope someone can help this as it is very frustrating.
