Description Dominik Haumann 2006-06-26 17:39:09 UTC

Version:           2.5.3 (using KDE 3.5.3, Gentoo)
Compiler:          gcc version 3.4.5 (Gentoo 3.4.5-r1, ssp-3.4.5-1.0, pie-8.7.9)
OS:                Linux (i686) release 2.6.16-suspend2-r5

Settings: dynamic word wrap and static word wrap off

1. Empty buffer
2. add a long line, so that you have to scroll horizontally.
3. go to end of line.
4. press SHIFT and go to the left, until you are at about column 80
5. press del

Now you can see that the scrollbar is disabled again (as the text fits into the view width), but the text is out of the view. A realignment of the text is missing.
