Problem

Symptoms: Random characters or numbers are missing from the display when running ScreenExtender SE version with WP 5.1+. The characters do not display on the status line, menus, or the document screen. Solutions: This problem will occur on systems running Stacker 4.0, 386Max memory manager and STACKHI.SYS loaded in the CONFIG.SYS. If the user is running Stacker 4.0 and losing characters in the document window, status line and menus, check to see if they are using 386MAX memory manager with STACKHI.SYS, if they are, the problem can be fixed by editing the ScreenExtender batch file and adding the following startup option to the first line of the ScreenExtender startup batch file in the WP51 directory: /Fblow/Fbuffer=10 Below is an example of a VGA ScreenExtender batch file: C:\SX\VSXWP(PLACE THE STARTUP OPTIONS HERE) C:\WP51\WP %1 %2 %3 %4 %5 %6 %7 %8 %9 C:\SX\VSXWP U /unload Fblow will place the font buffer in conventional memory. Because the default size of the font buffer is 64K, most users will either not have enough conventional memory to run WP. The Fbuffer=10 startup is added to decrease the size of the font buffer to 10K. How/Why: DPEMS.EXE loads Stacker into high memory, which causes a conflict with ScreenExtender SE (which also loads cache and buffers into high memory). Loading the font buffer low will correct the conflict problem. Changing the size of the font buffer to 10K should be sufficient for most users. If there is a problem with display speed after starting ScreenExtender with these startup options, increase the font buffer to 20K.
