Well, I got an email this morning saying that IE9 beta was available for download, so I decided to give it a shot. I'm running Win7 Enterprise 64-bit on my work laptop and have been wanting to run 64-bit browsers to see if the speed increase would be nice; however, I was shocked to find that Adobe did not have a 64-bit version of flash player - pretty much THE key component in making sure your web experience works (along with java).
Well, Adobe Labs has available their Flash Player codenamed "Square" that is for 64-bit browsers and has specific support for IE9 beta...and guess what? Not bad, not bad at all. I loaded up SharePoint, navigated to multiple pages, tested the loading of Explorer view and the client integration between Office and SharePoint and everything came out smooth thus far. It even advised me of one of my addons that was drastically slowing down my load times within IE...one that I forgot I had; so I disabled it and my browsing is a little faster. I did an Acid3 test and it came out at a 95, not too shabby though the animation was a little choppy. I didn't even have to load any of the pages in compatibility view.
EDIT: The address bar was bothering me because it was short and I couldn't find any options for changing the display; all you have to do is mouse over the right edge of the address bar and you can click n drag to widen or shorten the address bar. END EDIT
Anyone else experimenting with IE9 and SharePoint?
