In what must surely qualify as one of the more bizarre bugs in Windows 95 and 98, Microsoft Corp has discovered a fault which hangs the system – but only after 49.7 days of continuous operation. According to a report on Microsoft’s web site, the fault is caused by a problem with the timing algorithm in the Vtdapi.vxd file. There is a patch available, but Microsoft suggests that users wait for the next update that contains the fix unless they are severely affected by this specific problem.
