Troubleshooting
I Don't Want Word to Extend Selections
By default, Word uses smart paragraph selection. In other words, if you drag across a paragraph to select it, Word will automatically include the hidden end-of-paragraph marker in the selection area. This is for your own good, because it prevents you from leaving behind the paragraphs' marker inadvertently. Word also automatically selects an entire word when you drag across selections, so your selection doesn't stop in the middle of a word.
If you dislike either of these features, you can turn them off. Choose Office, Word Options, click Advanced, and in the Editing Options section, clear the Use Smart Paragraph Selection check box and/or the When Selecting, Automatically Select Entire Word check box.
I'd Like to Save Clipboard Content for Later Use
By far the easiest way to save something from the Clipboard is to paste it into Word (or some other application) and then save it in that application's native file format. But you can also save, organize, and recall items from the Windows Clipboard.
With a default installation of Office, a utility is installed called Microsoft Clip Organizer. It is primarily for managing clip art, but you can also use it to save items to and from the Clipboard.
You'll find it on the Start, All Programs, Microsoft Office, Microsoft Office Tools menu. Start it up, and then choose Edit, Paste to copy the current contents of the Windows Clipboard into the organizer. The pasted item appears as a thumbnail image there. You can drag it into any of the various collections on the Collection List, assign keywords to it, place it back on the Clipboard (with Edit, Copy), and more.
One thing you can't do with the Microsoft Clip Organizer, however, is to save the clip as a separate file. To do this, you need a different utility—the ClipBook Viewer. This is a Windows XP utility, not Office. (It is not available in Windows Vista.) In Windows XP, you can find it at this path: Windows\System32\clipbrd.exe. (Use the Run command to run it.)
The ClipBook Viewer starts out with a single, minimized window called Clipboard that contains the current contents of the Windows Clipboard. Restore this window and then choose Office, Save As to save that clip as an NT Clipboard File (with a .clp extension). To recall a saved Clipboard item, use Office, Open. This places the content of the file onto the Windows Clipboard, displacing what was there before.
The Building Blocks.dotx File is Corrupted
If you see a warning about the Building Blocks.dotx file being missing or corrupted, click OK. If asked whether you want to recover the data from the file, choose No. Then close Word, and use Windows to do a search for the file Building Blocks.dotx. Delete all instances of that file and reopen Word. Word will re-generate a fresh copy of the file. You will lose any building blocks you have created, however.
