Et tu, IE7?
My experiences are similar to Nariman's and indeed a lot of other folks - I have about three to five tabs open, browsing a variety of sites when the browser locks up. I attempt to close down the tabs, which seems to have little effect. Then, the browser suddenly disappears completely.
At first, I thought it could be an issue with WSS v3 synchronization since this seemed to be when the problems would present themselves most frequently. Then it started happening indiscriminantly.
I had quite high hopes for IE7 after following the
dev team's blog for over a year, and it seems certain that everyone on the team has a sincere desire to make a really excellent product. That said, inexplicable crashes seem somewhat sophomoric given the maturity of the platform and that its predecessor was nowhere near this unstable.
I anxiously await the next update/service pack release.
Microsoft Mashups
I certainly hope something meaningful is on the horizon, as I find the approach so far for developers fragmented. Yes, we can now code AJAX apps with UpdatePanels and make seamless XmlHttpRequests to webservices, but try writing a Virtual Earth mashup as quickly as a RubyOnRails developer can with Google Maps. There's still a lot to do to simplify the process.
