Hi all. I apply on-the-fly transformation to all the layers, for Mercator it works quite well but for Lambert and Albers,  I can't find the shp file which I used as background. I checked the zoom and found it was 14668457.9823389 or 13201612.184105..... in a word it is big. The map(shp file) still diapeared but I found that the shape of the map was not disapear. It is there but the shape changed a lot ,I can bearly recognise even some parts are not shown in the picture. Any one meet this kind of things before?

Hi all. I apply on-the-fly transformation to all the layers, for Mercator it works quite well but for Lambert and Albers, some strange thing happened. I can't find the shp file which I used as background. I checked the zoom and found it was 14668457.9823389 or 13201612.184105..... in a word it is big. I think this maybe the reason for the strange thing. Please give me some light on this, I am confused.

I tried again, the map(shp file) still diapeared but I found that the shape of the map was not disapear. It is there but the shape changed a lot ,I can bearly pick it out . However , some other part of the map maybe only the line to define the border of the country is lost  . Any one meet this kind of things before?
