#19 Non consitent behavior, application seems to freeze

[Raphael Noeldner]

Sometime application freezes and does not react anymore, needs to be kill process with task manger.
Doing the same after a restart, all is good.
Assuming some async routines are not returning to the correct thread, leaving the Ui thread in undefníned state.
Debugging and Fixing is difficult, as this is not very reproduceable.
