Dear community,

i am dealing with a really standard webview in a b4j splitpane, nothing special at all.
(loaded site is youtube.com, but i think that did not matter, no video playing, just browsing through..)

from time to time i am getting a fatal error of the jvm.
i cant reproduce it, but i think i am doing a mouseclick short before!
I am also thinking, that this is not a B4J Problem :D. I am sure!!!
Also not of my b4j code i think. there is nothing speciall, just logging the clicked elements on the b4j console.

As the logs says: a native lib error.

But maybe someone out there knows something about and could give me a hint.
Here is the B4J error log:

# A fatal error has been detected by the Java Runtime Environment:

i also thought about.
but i am not sure if this would be the best solution (if it works at all), because if i would deploy everyone needs 64Bit Win!?

maybe i try another webengine. cssbox sounds well promising.
or do anyone know another (better) one?
