[mapserver-users] IE/Windows mis-registered clicks

[lfilak at medinaco.org]

We have been having a persistent problem which seems to be occurring more 
with the advent of MS-Windows 7. We were able to track the problem down in 
MS-Windows XP some time ago and could provide users with an easy fix but 
now the setting changes needed under Vista & 7 are more cumbersome. We 
found that a user running XP, using IE, and who had changed their screen 
DPI from "Normal Size" to "Large Size" could not click on the map image and 
have IE return valid pixel coordinates. When the user picked on pixel 
400,400 of the map image IE would return something like 200,200. I'm sure 
it's the difference between the default 96DPI and their modified 120DPI. 
Unfortunately the problem is not easily reproducible in XP and only seems 
to effect XP installs that have undergone some sort of "update", but we 
don't know what. With 7 I'm beginning to wonder if every user of our site 
using 7 & IE is having issues. At least with XP the one case I was able to 
study proved that it effected not just our site but google maps also, but 
with 7 I can't verify anything. Is anyone else experiencing this issue and 
have a fix?
Thanks in advance!
