First of all, even though this is a beta, load speeds seem to be improved for our huge project. Even better, the random 1-2 minute hang (while the disk churns, probably GCing) seems to be gone. Overall I'm liking the new version, looks like a nice improvement (esp. the more extensive code formatting and the team shareable settings and templates). Good job!
My first problem I've encountered is this: our files are readonly due to the source control that we use. When first editing a readonly file, R#2 pops up a dialog asking if I want to modify the file (vs. VS.NET's doing it at save time I believe). Unfortunately I checked the checkbox to not show that dialog any more. Now when I try to edit a readonly file, VS.NET just dings at me. I didn't see any setting in the options dialong or UserSettings.xml, so I'm wondering how I can get back that dialog, or disable this R#2 feature.
