i am using a wms overlay in the gis module, sometimes pink tiles appears, if i right click on this tile and click on show in a new tab, the image is properly loaded in a new tab. I am wondering if there is a timeout in the client side that prevent displaying tiles which are loaded for a long time. i tested on IE8, firefox 3.5 and chrome.
More generally, what is the possible cause to get a pink tile ? do you have a list of possible mistake that causes this problem?
thanks for your help
