I recently reinstalled my Ubuntu on my computer and gnuplot is showing some very strange behaviour.
If when typing a command it goes into a new line (ie. soft return) I can no longer go back to the previous line. Backspace doesn't work, back arrow or ^B don't work either.
I've also noticed that if I use the back arrow to try to reach the previous line then press the forward arrow it will append the last few characters from the previous line to the front of the current line. The number of characters appended seems to depend on how many times I press the back arrow. Using backspace at the front of the line seems to stop this particular behaviour.
I have no idea how to fix this, so any help would be very much appreciated. Thank you.
