1. NCSA 1.5.1 imagemap problems
We're having an odd problem here with our imagemap.
I just did a binary-only upgrade from NCSA 1.5a to 1.5.1. Since then
(at least I think the problem dates to that change), our home page
imagemap seems to have "holes" in the space.
We didn't change the map file at all -- it's been the same for
months. I did change the image, but it has the same dimensions and
layout as the old one, and I've made similar changes before.
I checked out the coordinates in the imagemap file and they check
out within a pixel or two. The map file is correct.
But when I click on a "button" in the imagemap, if I go to some
parts of it, it gives me the default. If I move slightly to one side
or the other, it works. Sometimes there's a dead spot right smack in
the middle of the "button".
I've replaced the imagemap executable as well with the one that came
with 1.5.1, just in case there was some weird compatibility problem,
but it didn't help.
Here's an example. On the home page, we have a large image over
which some "buttons" appear. Here's a section of the map file:
rect http://www.upenn.edu/calendar/ 235,282 317,304
rect http://www.upenn.edu/grad.html 245,0 470,308
There's more to it, but this is just for my example. If I click on
coordinates 278,290, I get the grad.html page, not the calendar
page. If I click on 307,290 I get the default page. If I click on
278,291, though, it works properly. Same for 278,289. It appears in
this particular case that I have a pixel-wide line through this
"button" that doesn't work. A similar phenomenon occurs throughout
the page, though I haven't ascertained whether they're lines or dots
that don't work.
I can't emphasize enough that this map file *worked* up until
earlier this month. It was in place before I arrived here, for
months, with no problems at all. We've also had the entries in the
map file in the same order the whole time.
Can someone out there help me with this? It's an odd one...
Thanks in advance..
