NVidia Control Panel 7.4.74 (most current) does not have the menu option they suggest using. Can not find anyway to disable the 3D issue in FSX. I contacted NVidia and they said use the cntrl+t keys to turn on/off the 3D.
IRS Form W-9 is most commonly used by individuals when they are working as a freelancer or independent contractor. If you ever find yourself filling out a Form W-9, it generally means that a business or person who is paying you money needs your Social Security number so it can notify the IRS of the amount.
When you're a contractor, instead of a W-2 you get a separate Form 1099-MISC detailing what you made for each individual job. The IRS gets copies, too. But an employer does not have to send you, the independent contractor, a 1099 if you made less than $600 during the tax year.
