It would appear that there is yet another bug in Apple's browser for Windows.

This time it's with pasting a URL into the address field.

Safari 5.0.1 for Windows XP SP3 has a bug that won't allow a URL to be pasted

into the address field via the paste command as invoked through the

application's menus.  The steps below identify how to reproduce the error.

1. •Click in the address field to select the contents
   

2. •Right-click | Paste or choose Edit | Paste to paste in the new URL
   

3. •Press the Enter key on the keyboard or click the reload icon in the address
   

4. •field
   

5. •Nothing
   

If the URL is pasted into the address field via the keyboard command (Control+V)

the page will load as expected.

UPDATE:  This bug affects Windows 7 as well.
