A few users reported that with Web projects located on a remote machine closing project or solution may hang Visual Studio and Visual Web Developer Express for several minutes. We fould that the issue may be caused by VS logging component that collects information on product usage. This is an opt-in feature activated in Help | Customer Feedback Options… The feature may cause logger to walk through folders on a remote server calculating project complexity. The feature does NOT send your project to Microsoft, it just collects some statistics on the project. If you are experiencing slow project close, try switching off participation in the feedback program in  Help | Customer Feedback Options… dialog. If it does not help, try disabling component in registry by changing

HKEY_LOCAL_MACHINESOFTWAREMicrosoftVisualStudio9.0Packages{2DC9DAA9-7F2D-11d2-9BFC-00C04F9901D1}

to

HKEY_LOCAL_MACHINESOFTWAREMicrosoftVisualStudio9.0PackagesDisabled-{2DC9DAA9-7F2D-11d2-9BFC-00C04F9901D1}

Thanks
