I am having an issue which did not exist in Windows XP or Windows 2003. The problem is quite simple. If there is any word or letter which has hyphens and you want to Select it by double clicking it does not select in Win 7 . Example 11-1111111-11111 Try yourself by double clicking on it. You will not be able to select full range. But try again in xp or 2003 you will be able to select entire range. Same applies to words This happens in Windows and I do not see this happening in Firefox.
