ArgumentOutOfRangeException when saving changes to GlobalSuppressions file.

You deserve serious credit for the community contributions and youtube content you create; I'm always impressed. Tweakster is great. Thank you!

I hit an ArgumentOutOfRange exception quite a bit since installing Tweakster. I often add items to a GlobalSuppressions.cs file for any number of suggestions that VS provides. This error is thrown when modifying a recently opened GlobalSuppressions file once I have made changes.

Detailed Description:

I use CodeRush to invoke it's context menu which includes both CodeRush and VS suggestions (Ctrl+~). I then navigate by keyboard to the VS suggestion to suppress the issue into a GlobalSupression.cs file. The GlobalSuppression file is opened and I navigate to the text and enter my reason for the suppression and the exception is thrown.

By reading the ActivityLog I can see the exception is thrown in CollapseAttributeTagger. I am therefore able to work around this issue by disabling "Enable collapsing attributes" in the Tweaks options page.
