Infrastructure Software

We're running SGD Enterprise Edition with a number of Microsoft and non-Microsoft applications. I've noticed that when I'm logged into Outlook through Tarantella and running a different application through Tarantella, I don't get my Outlook notifications when I receive new emails. If I manually open the Outlook window, I see the notification, but I can't seem to find an automatic way to display the email notification no matter what window is open. I'm basically looking to run Outlook in the same manner as if it was loaded locally on my machine, in a way that the email notification window pops up no matter what application I'm actively running.

Anyone run into this? Is this a common issue with running this type of architecture? Thanks
