Office 2007, updated with all Service Packs and patches. All other file extensions open fine with exception of ".doc". When opening a .doc file, (for example, "sample.doc"), I get error message that states "The command cannot be performed because a dialog box is open." Click OK, and dialog box behind it states "The file could not be found. (C:\Documents.doc)". Click OK and new box says: "This file could not be found. (C:\Documents and Settings\...\and.doc)". Click OK and new box says: "The directory name is not valid. (C:\Documents and Settings\...\sample.doc)." Click OK and document finally opens.



Can someone help resolve this issue?
