Unfortunately, the bug is probably inside PMSHELL. I don't know if it might be possible to modify XWorkplace to deal with this somehow...

In order to successfully install eComStation 2.1, please take into consideration the following;

☆CPU
最小 Intel Pentium 133 MHz or equivalent
(including Intel Celeron, PIII, P4 and
AMD K6, Athlon and Duron processors)
推奨 Any modern CPU will do, but the higher the speed the more responsive your system will be. Also, the latest multi-core CPU systems should be supported. This is made possible by ACPI, but eComStation can also run on multi-core CPU's without using the other cores.

☆メモリ
最小 96 MB (absolute minimum required for
installation from CD).
推奨 Install as much memory as you can in your system. 4 GB is the maximum supported amount.
Applications like Firefox and Open Office need a lot of RAM to work. Also make certain you give a virtual machine (like Virtual PC) enough memory.

☆ビデオ
最小 PCI VGA video card with at least 512 KB
memory.
推奨 For more information, refer to the video card section of Chapter 4, “Hardware Supported by eComStation 2.1”, in this QuickGuide.

☆空き容量
最小 600 MB
推奨 When selecting more options in the installer, more drive space is required. A practical working size is a bootable JFS partition of 4 GB.

☆マウス
最小 Mouse Any PS/2, serial or USB mouse
推奨 A PS/2 or USB mouse is recommended for best performance.
