Hej sbillard,
sorry, but my study - regarding the browser- seems to be not correct.
It worked several times good with the IE 9.0 but now i have the same problems again.
My newest observational researches are that if there are less than 8 images in a folder everything works fine. If there are more than 8 or 9 the error message occurs.
I asked my provider, but he does not know something about that you wrote in your first answer.
I checked my settings to every album to be "10", but there is no difference between "10" or "20" images. (i tried that)
At this time i can´t manage my folders with more than 8 images and that makes me a little bit sad.
Do you have some other solution or a workaround in your "pocket"??
Thanks for help.
