In Windows 3.11 upgrade some of the core files were updated to fix some minor problems listed below.
COMMDLG.DLL - was modified to allow Windows-based programs on diskless workstations to use the common dialog boxes provided by this DLL
GDI.EXE - was changed to help programmers using graphics calls, especially those calling the "draw rectangle" function.
KRNL386.EXE - was slightly modified to prevent problems that may occur when third-party software calls for windows to shut down before focus returns to Program Manager.
PSCRIPT.DRV and UNIDRV.DLL- were updated to eliminate a problem that occurs in Windows 3.1 when a word processor uses more than 60 fonts in a single document.
VTDA.386 - solves a timer- related problem that sometimes occurs when you start an MS-DOS-based application on a Novell NetWare network. This problem occurs a very small percentage of the time under Windows 3.1, and shows up usually as Windows crashing to a black screen with a blinking green bar in the top left corner. This problem is also referred to by Novell and Microsoft as the "Black Screen of Death".
