I had been running TB 1.0.2 on an XP Pro laptop for many years with an admin and a non-admin account. I recently upgraded it to Win 7 and installed the latest TB (27 or something). As I was adding e-mail addresses through the non-admin account, suddenly all but two addresses disappeared from the left pane. However, when I opened Tools/Account Settings, I saw all the accounts still listed on its left pane. I also noticed a "Unified Folders" at the bottom which I had never seem before. I found a View tab which gave me several options including All but although I tinkered with it several times, I could not make the full address list appear. Since I found the new version too cryptic and the old 1.0.2 was unavailable, I uninstalled TB and installed 1.0.7 which looked very familiar except that the Unified Folders was still visible in the non-admin account but not in the admin account. I uninstalled/re-installed 1.0.7 and still the Unified Folder seemed to get re-generated automatically in the non-admin account but not in the admin account. Tools/Account Settings shows its address as C:\Users\Dave\AppData\Roaming\Thunderbird\Profiles\ptntwaz9.default\Mail\smart mailboxes and also deactivates the Remove Account button for this folder. I am afraid to enter the addresses, not knowing what this Unified Folders would do since I no longer had a View tab or any other control over it. So my question is - is there any way to get rid of the Unified Folders from TB 1.0.7? Any help will be appreciated.
