Cannot delete view-private file

Cannot delete view-private file

In a dynamic ClearCase view on Windows 7, I've got a file with size 0 and
name myproject.prj.$$$. I cannot open, delete, rename or modify that file.
I'd prefer to delete the file, but when trying to delete it:
Windows Explorer shows the error message "Invalid MS-DOS function".
cmd.exe's del: "Incorrect function".
ClearCase Explorer simply does nothing.
I've created a file with the same name at a different location, and was
able to edit and delete that file without any issues - so I guess the file
name is not the issue. The file first showed up after the computer had
crashed. I'd prefer not to delete and recreate the view.
What can I do to delete this file?
