"Refresh" mode is used to handle such apps.  Executor has an
"autorefresh" feature which checks every second or two to see if
refresh mode needs to be turned on.

Yes, it will be very fast.  To do this you need not only VBE 2.0's
linear frame buffer, but also you must run Executor under plain DOS
using cwsdpmi.exe.  Windows and Warp don't implement the DPMI 1.0
standard which we need to access video hardware more directly.
