Thanks. Should have known that.
Two items on update. (but, as before, I may be jumping the gun).
WP 3.2.1 p2 1.31 (Browsers– Safari, Firefox) no plugins.
1) On front-page (when logged in) clicking the “Reply” button prompts a popup ” Whoops look like you are not connected to the server. p2 couldn’t connect to WordPress” then you are redirected to the post page. Also in Firefox. “Looks like you are not logged in”
2) With the plugin Front End Editor activated (no other plugins activated) .When posting from front page a pop-up appears “Are you sure you want to leave this page.Your comments or posts will be lost if you continue. Click OK to leave this page, or Cancel to stay on this page.” In Firefox ” Are you sure? This page is asking you to confirm that you want to leave – data you have entered may not be saved.”
Thought it might me related to my own computer but p2 1.2.3 does do any of this on same machine.
