Hello.\n\nI got my guts up to try IE7 Beta 3 on XP SP2. Previously, I was running IE6\nwith an installed Yahoo Toolbar with Pop-up Blocker from Y!Messenger 7.5, and\nwith the other stuff installed (Browser Services, Mail and Install Manager\nAFAIK?). Maybe I should have uninstalled those, but I didn't, because I\nthought it would be fine, and it wasn't listed on the release notes. Then I\ninstalled IE7 B3.\n\nAfter installation, I couldn't get Quick Tabs, or even normal Tabs to work.\nThe Command Bar doesn't show up. Enabling an Explorer Bar would crash IE7 B3\n(Sorry, forgot the module name where it fails... ^_^). First I tried\ndisabling all add-ons through the Advanced Options (RIES?), maybe it would\ngo. But no go. So I tried de-installing the Yahoo add-ons except Messenger.\nStill no go. And so, I tried de-installing and re-installing IE7 B3.\n\nAfter re-installation, I tried fiddling around with the Tabbed Browsing\nOptions. Disabling it would enable the Command Bar, and the other Explorer\nBars (Favorites, Research...). Now I am running it with Tabs disabled. I\nhaven't tried running it with Tabs on since.\n\nThis is just fairly recent, around 3 days ago. No previous IE7 Beta running\nexperience. PC is a loaner one. MS Software installed is MSO 2003 and now,\nIE7 B3. Add-ons, well, are the common Flash, Acrobat Reader and Java ones.\n\nUnderstandable as it is running a BETA vs a STABLE version, I just got\ncurious and asked. Maybe someone else has this thing goin' on.\n\nThanks for your time.
