Hi Don,
thanks for answering my mail.
I tried it out and eliminated nearly all setCapability()-statements from
my code.
The result was: nothing changed. Then I ran at the examples from Sun,
which rendered fast, and looked at their code to see what is diffrent,
and
what can be the reason for the slow rendering of my app.
The end of my (quite few) efforts: my app runs fast again now, but I
don't know what
made the diffrence.
I leave it to some magic ... :)
regards
Britt
