Clipper will run as fast as a Dos shell in a Win x will allow, and depends , overall, with the processor speed.
You can "fix" "Win me" editing system.ini (pervmfiles),
But what about (for example) Win 2000: you'll need at least a 6.0 blinker to make the app run without problems. And this "new" apps will run backward to Win 95, as an example?.
As many friends said: "clipper is touching the fan". But touching the fan, relay on the future of companys that support Clipper.
Evolution. For we (and I), lovers of Clippers, must realize that we are in "the hands" of people who write compilers, linkers, lybraries, for Clipper.
We must be in close view of what is happening about Clipper support.
In short: isn't a bad idea to migrate to ME, but this is a matter of "operating system marketing". The concepts are others.
