This article is from the GNU Chess and XBoard FAQ, by Tim Mann email@example.com with numerous contributions by others.
Most people don't have this problem, but two or three people using
Windows NT 4.0 with Service Pack 3 or 4 have reported it. I have no idea
what causes this problem. Contrary to what was reported in a previous
version of this FAQ, reinstalling the service pack after installing
WinBoard does not seem to solve the problem.
