Visual Studio Achievement plugin causes files to be locked and then our build fails

We have found that the plugin causes files to become locked and that then causes the next build to fail! Anyone else seen this or have any workarounds? We are using Windows 7 64bit and Windows 2008 R2.

The error message mentions something about open user-mapped sections!?

Disabling or uninstalling the plugin fixes the issue. Has occurred on all our developers machines

Know issue,.. They are working on it,..

I get this error on Publish only when plugin is enabled
