That's sad!

As I said, I don't have lot's of knowledge about these things, so I was 
expecting the switch to Mercator solves problems instead of creating new 
:-(((

If switching to Mercator means that we cannot use landsat images, I'll 
tend to switch back to EPSG. Landsat is the only WMS that I can use here 
in Nürnberg and loosing this opportunity (how ever "low resolution" 
these pictures might be) is not worth to have "circular circles" IMHO.

This happens if a developer develops things he has no real clue about ;-)

P.S: Nonetheless, improving the WMS plugin to show a warning if the 
projection doesn't match the WMS capabilities, seems to be a *very* good 
idea to me. I guess there are more mappers out there that don't have a 
real clue about the projection and getting "strange" WMS images because 
of wrong projection is probably not very intuitive and not the best way 
to deal with this ...
