Missing SessionId at the begining in FUSION 2

[Rodolfo Moreno]

Hi All, my thememain.aspx page which is inside of the taskpane widget rises an error in the first time that the application is loaded because Fusion 2 is not sending the sessionId. However the itself page works appropiately when I select it from the TaskContextMenu, after of the first loading.
This same application works well with Fusion 1.x.

my current enviroment: W2K3 + IIS6 + MGOS 2.1 + FUSION 2
my old enviroment where my application works well was: W2K3 + IIS6 + MGOS 2.0.2 + FUSION 1.X

Any help woul be appreaciated.
