i've got an issue with a map using map fields marker. it used to work the whole time but suddenly stopped showing (no map at all). after some investigating:

- i do use exposed filters and as soon as i use them to filter the map the map and markers are shown
- without filtering (-> showing all nodes) the map displays fine when i remove one field (a teaser text) i use for the marker's minimized content
- activating this teaser for the markers BUT limiting the number of items in the views setting also results in correct behaviour

so as a conclusion- it seems to be the amount of data used for the markers? is there any (memory) limit? is the data for all markers loaded at once?
i talk about some hundred nodes using title, a small image and a teasertext for each of them as marker content.
any help appreciated!
