Thank you for your post.
What is the web page being loaded by the WebViewer?
Which version of Internet Explorer is installed in Windows 7? This affects the how the WebViewer interprets web pages. On a side note, there have been a few reports related to Internet Explorer 11 and FileMaker Pro 13.
thanks for reply.
Web pages being loaded in the upper Screenshot (X) are [ http://www.medicalbizz.ch/add/intro_dt/intro2/intro2.html ] and same hrefs with 1 OR 3 OR 4 instead of 2. They look perfect in MSIE 11.
The html-protocoll for the "Anmelden" window is a calculated code where the animated-gif was converted into a Base-64 protocol
I'm using Explorer 11 v.11.0.9600.16428
There's a answer to that issue with the embedded graphic not loading (the logo's "MedicalBizz" and "CoverCard"): I increased the Windows 7 partition in Parallels and the issue seem to be resolved.This might indicate a change with caching and writing data's between FMA12 AND FMA13.
Though for both incidents definitely different behavior in FMA12 (no conflict) and FMA13 (WV and need for more memory)
