***************************************************************

If running an IBM Thinkpad 755 (docking station) with 928Movie,
the system may lock up when playing back AVI files which are
stretched. All interupts will be locked (mouse frozen, Num Lock
frozen, Ctrl+Alt+Del has no effect).

Consultation with IBM Japan has highlighted that this happens
because Hidden Refresh is enabled by default on the Thinkpad.
If Hidden Refresh is disabled, then the system runs perfectly.

Unfortunately, there is no way to disable Hidden Refresh within
the machine, so we have provided this application which sets
the necessary bit in one of the Thinkpad registers to disable
Hidden Refresh.

Note that the application is NOT a TSR, and therefore will take
up no memory.

INSTALLATION
------------

Copy the DHREFSH.EXE file into a directory on your path (e.g. C:\DOS),
and run it when required, or add the line

DHREFSH.EXE

to the end of your AUTOEXEC.BAT to ensure that the system works
every time.
