The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: A customer experiences the Sticking Shift Key problem with the EMM386 Expanded memory driver. The customer needs EMM386 loaded for expanded memory. Solutions: The Sticking Shift Key problem can be caused by EMM386.EXE, HIMEM.SYS, and QEMM386.SYS memory managers. Many people need these loaded to run certain kinds of software. Here are some options that may fix the problem without removing the memory managers. Before trying any of the options below, MAKE SURE THE CUSTOMER HAS A BOOTABLE DISKETTE AVAILABLE. This is necessary because many of the options below can lock the computer at startup. If the problem is caused by EMM386.EXE, try a different version. For example, if the version that came with Windows 3.1 causes the problem, replace it with the 386EMM that came with DOS 5.0 or Windows 3.0 (check the dates to make sure they are different). If the problem is caused by HIMEM.SYS, try a different version (HIMEM.SYS comes with Windows 3.0, 3.1, and DOS 5.0). If that does not work, try using the /Machine:X option with HIMEM.SYS where "X" is the machine type. Check your DOS 5.0 manual for available options. If the problem is caused by QEMM386.SYS, try using the IGNOREA20 and UNUSUAL8042 options (have customer's check their manual for proper usage). The IA option may also fix the problem. See Folio Memo EDT_070 in the WP51 infobase for additional options. |
