I'm using telerik rad map in my project with png and tiff Images,
this wired thing happens to me, every few times I run my code I get system invalidoperationexception in mscorlib dll,
it is definitely related to maps Images because when I remove the png and tiff (using the map without image) it is not happening.
please note that most of the time code runs correctly with the images.
do you have any Idea why some time I get this exception?
