I am experiencing difficulties with this method. Perhaps it would be better to do a standalone IE6? Anyway, trying the Home button or anything else on that toolbar area spits out an error message:
UpdaterUI.exe - Entry Point Not Found
"The procedure entry point InternetGetSecurityInfoByUrlW could not be located in the dynamic link library WININET.dll."
When IE7 starts up, it offers various options. Trying to change the language via the drop down menu results in a blocked pop-up! From then on, you can't use the menu. Nor any other links, or the Favorites button, until you leave that page.
OK, so I go to my home page, a local HTML file and try a link to another local file. It said it couldn't load it! I don't get that one.
So I hit the web, where I find scrolling is watery, especially on zoomed pages. Zooming also fails to enlarge the background images, making a mess of my work site! Input buttons are also larger for some reason.
Hovering over some text while zoomed also flickered between two sizes.
So I tried the New Tab button, only to see an error come up that there was no page to display! Er... yes, because I've not loaded one yet.
I quite like the Quick Tabs screen, only the scrollbar there doesn't use XP's generic styling, but the old Windows look. (Horrid to me.)
I also see problems on web pages that appear identical in all other main Windows browsers. Luckily my personal site looks OK!
If this is the best Microsoft can come up with (and yes I know it's still a beta) I'd be seriously worried. Firefox runs rings around this. There's no way people will convert back if IE7 is as poor as this.
I will await further releases to see if it improves.
