That's good news, though looking at the following it is hard to work out=20
why....

OK

OK, so that narrows it to the PNG code.

So, it had nothing to do with that.

imagedatasource is unrelated to this problem (its for reading images) so it=

should have no effect on anything.

Its hard to see that anything at all has changed, you have gone back to the=
=20
original jar file and none of the other steps change anything...

>I don't what thinking of that, hope it gives you hints ?

Its a little hard to say what the problem might have been, I'm glad that it=
=20
is working for you now though.

If the problem comes back please don't hesitate to let us know, the more=20
feedback we get the better :)
