Screenshots

When I delete text under Scientific Workplace, the end of the line is not
treated correctly. Was is most evident is that the last character(s) is(are)
not canceled.

I attach a vertical concatenation of 3 screenshots:
the first is the state before hitting backspace: I typed "abcdefghijkl" and
added an inline image,
the second is after hitting backspace (I cancel the "g"); notice how the last
"kl" are not correctly canceled and the image is not moved to the left
and the third is how it should have looked.

No error message is displayed while hitting backspace (it complains about IME
all the time but I think it's no big deal).

I have seen this problem at least in versions 1.0.1 (under Debian testing,
Ubuntu hardy and intrepid, both 32 and 64 bits) and 1.0.13 (Debian testing 64
bits). The situation is even worse under Ubuntu intrepid (32 bits OS, Wine
v1.0.1) as text disappears as soon as it is typed (Esc redisplays it briefly).

I can live with the image (visible at the end of the line) not correctly
positioned after backspace (it seldom occurs), but the last character not
canceled is a real (visual) pain.

I can test anything you wish and I understand programming/debugging.

Thank you for any help.
