New Post: C#: R.NET shuts down if I use it in a task

Hi,
to have success with an computationally intensive calculation I had to make a new task.
Directly after the calculation there should be initialized a R.NET plot. The plot actually was shown, but the problem is that the window with the plot exists only for 10 seconds. Then I get the message "no callback" (on German: "Keine Rückmeldung") from the window and it closes itself.

If I call the R.NET-command outside a new task, it works. Do you have any ideas?
