Bug#550237: vim: mouse clicks produce bogus, if clicked too far to the right.

Package: vim
Version: 2:7.2.245-2
Severity: normal


I am using quite a large screen (1920x1200) and if I enable mouse support in vim (:set mouse=a, in my case its in ~/.vimrc), I get wierd results, when I try to use the mouse on the far right side of the screen. By wierd I mean, that the clicks are not registred as clicks but as key presses. The keys pressed are mostly harmless, but it inserts text or deletes lines or does things according to which key was just recognized.

To reproduce this, open vim on a wide screen (two screens will do, too) or with a very tiny (narrow) font. And write a long line. On my screen the clicks are no longer correctly registered after the 223rd column of text, so clicking on the 224th or any later column brakes the mouse support.

It has obviously something to do with the 223 columns, because, when I increase the font size, to something, so no 223 columns have room on the screen, the error is no longer there. When i decrease the size, the limit for the mouse moves further to the left.

By the way: I had the sam eproblem on an x86 32Bit machine, but I thought it was a problem with my dual head setup. Now I am using only one screen and get the same problem.
