- What kind of a computer are you using? A 386/25 or something? What in the
- WORLD makes you think your 386 should be faster than a Sparc?? Geez. I'm
- sick of all you people with 386/16s running them at 1024x768, and then crying
- about the slow speed of DOS Windows. Have you ever tried the DOS Windows in
- Win3.1? They are exactly as slow (or as fast, in my case). If you want
- your scrolling to be fast, get a new graphics card or a new computer, or
- reduce your resolution!
-
- Quit crying. It's YOUR hardware, NOT OS/2!!
-
- On my 486, with ET4000, the DOS window scrolling is pretty quick.
