29. The map shows up, but not the markers!
Trying clearing your browser cache. We update the site frequently, so you may be using an older version of our site. If the Frappr is large, it may take a while for markers to load.
30. Which browsers are supported?
We test the site with Microsoft Internet Explorer 6.0 and Mozilla Firefox 1.0.7. We heard Macs are working fine now (not sure though). Not too sure about Opera.
