- I've been having similar problems with vi, but the screen goes haywire when
- I'm going up and down the screen, not across. Somehow TE/2 acts like it is
- interpreting the "move cursor up" command like a return, so the top of the
- screen stays fixed and the bottom goes down, leaving the cursor where it was.
- Not as frequently, but similarly when typing in something the return at the
- end of the line causes the cursor to go down, but not move the text below it
- down. This seems to happen when inserting text in the middle of the screen.
- However, if I have VI wordwrap for me, it usually doesn't do that.
-
- That's why I don't buy the tab thing. Maybe I've got a different problem.
- Note that I just re-downloaded TE/2 from Hobbes a couple days ago and it still
- does this. The backspace in TE/2.INI is also set to non-destructive...
- Finally, I'm only running this on a 2400 baud modem, no compression or anything.
- I also have problems (as in can't) download stuff and launch anything big like
- a WinOS/2 session without TE/2 saying File Transfer Failed, and when I go back
- it's always frozen. It'll take Alt- commands, but even after hangup and redial
- won't transmit any text...
-
- Any clues?
