Word is NOT read only!

[kinook]

1) 'Tools | Options | Documents | File extensions to open store documents writeable' Determines which file types are made non-read-only on disk when a temporary copy of a stored document is created.

2) 'Tools | Options | Browser | File extensions to display in internal browser view' determines which stored document types are displayed internally (in their associated application, if it supports embedding).

3) If not included in the above option, UR can parse text from the document, and 'Tools | Options | Editor | Show item text for documents with no viewer' is checked, the document's unformatted text will be displayed internally (the document can still be viewed/edited externally via Item | Open Document or Ctrl+J).

So if you don't want Word documents to be edited/viewed internally, remove .doc from #2 and uncheck #3.
