>>Isn't that the original VS2008 version?. SP1 was released sometime, I think, in the last couple of weeks. That's the upgrade I'd just installed (and the one I thought you were referring to) : 9.0.30729.1 SP. There's an updated framework as well.

Seems to me that the build process takes longer with SP1 installed. The 'Build succeeded' message appears quite quickly but there's a delay after that before the cursor becomes responsive again. Also the entire 'Solution Explorer' pane somethimes repaints itself. But this happens on a solution that is using a remote web server for source control so that may be a factor ?
