<font size="-1"><font face="Verdana">A couple of problems I can
think of right now.<br>
<br>
* The slowness of vector layer in IE without Canvas support (up
to IE8, I guess?).<br>
Zac mentioned performance warnings when adding more than
1000 objects. I get problems with IE7 when adding more than 100
objects. In my case they are text labels each constructed of two
VML elements. They could theoretically be replaced by DIV
elements, but probably better just wait for people to upgrade
their browsers. A workaround is to measure and control the
performance by OL library user script.<br>
<br>
* The clumsy (not strightforward) way to get a marker (not
necessarily meaning the Marker class here) on a map that display
an info pop-up upon a mouse click.<br>
I've seen many posts where people are asking help on
this, even though it would seem one of the basic features one
would want to do with a map. In addition, it seems that there
are several ways to do it, some official examples offered are
out-dated and actually supposed to be deprecated (the Markers
layers altogether, as I understand), and some functions
supposedly (as per documentation) creating pop-ups do not work
or do not work as it would seem they should.<br>

<pre wrap="">Hi all,
for my talk "Common pitfalls for users of OpenLayers" [1] at this years
FOSS4G [2] I want to evaluate the parts of OpenLayers where users of the
library experience problems.
You would help me -- and the project itself -- a lot if you could answer
in this thread and tell me what problems you had working with OpenLayers.
Please do not hesitate to tell us what has bugged you, what was unclear
or non-intuitive. Provide us with the sall and the big annoyances Of
course you are heavily encouraged to provide ways around the pitfalls
and possible enhancements.
I want to identify areas which often cause problems... and eventually I
plan on making the library better where this is possible.
Anyone is invited to share his/her thoughts -- so if you want the
library to improve, go on and tell us where we can make things better.
Thanks in advance,
Marc
