Dear Mike,
Here are some news:
I have tested the S5 Tab Show show on iPad Mini and iPad Retina. Those tablet runs perfectly.
The earlier mentioned iPad and Samsung tablets are older tablets with lower resolution.
Maybe the problem is restricted to the resolution only. If you agree - is there a workaround e.g. changes in the CSS file ?
If not the problem will solve itself at time
Thanks for your kind efforts
Best regards Peter
