Can't delete files. System complaints of "Invalid Parameter"
Hey folks,
Today, when trying to delete a file, my system began complaining of an "Invalid Parameter". After this, although links to the file are deleted, the file still appears in the Project view. Additionally, when trying to check in my changes, the system complains that the "ImageSize.Width" parameter is set to 272, and the value should be from 1 to 256.
But I haven't touched any images today. In fact, all I've done today is work on a Table of Contents and Conditional Build Tags. This error is brand new, and I'm not even sure where it's coming from. (I did a search for "ImageSize.Width" and didn't find anything in any file.)

This error appears every time I try to delete a file now. I've tried this with 4 different files, and it happens with all. After the error appears, I can't even check in my changes to my versioning system (TFS); I have to restart the application to check changes in. Additionally, the file remains in the project manager.
Any help is appreciated.
