Hi Folks, I have a very strange behavior occurring since the last update. I have 11 email accounts and have one unified 'Inbox' at the top of the tree listing these email accounts (in the left pane). I can no longer click on the top level unified 'Inbox' - it simply does not register a mouse click at all. I can click on any account displayed in the tree below 'Inbox' and that works fine, I can then manually (using the keyboard arrows) navigate up to the unified 'Inbox' and this works fine, displaying everything in the unified 'Inbox' as it should. I have tried deleting the 'smart mailboxes' folder and restarting and while this re-creates the 'smart mailboxes' folder, the problem is still there. It just appears that the top level unfied 'Inbox' stubbornly refuses to recognise the mouseClick (or even mouseHover) event. I have also noticed that double_click on 'Inbox' will minimise from full screen to window mode and vice versa, a behaviour I am not sure is correct either... Any help would be greatly appreciated as this has become increasingly frustrating to work with. Best regards to all, Carl
