Besides from the usual frustrations I encounter in my day to day live developing webapplications which SHOULD also work on Internet Explorer, I just found another little reason to drop IE from my support list.
Why? I just had a discussion with my customer explaining that the reason why some stuff failed to work was the trailing space in a @id attribute. Firefox for instance shows the data as it should.. untouched. The customer however was a bit frustrated because when he opened the xml file in IE, he did not see the trailing space so we ended up in a small yes-no discussion ;-)
Lesson learned: Be carefull when debugging issues using Internet Explorer.
Do you really consider this a feature... or is this just one of many bugs?
