Popup triggered on mashup load
I have a master mashup with a main menu that can lead to several different pages. When I first load the application, I want a navigation button triggered that pops up a mashup that the user can select a few items that will drive the rest of the mashups. My issue is that if I trigger the popup on mashup load, every time a user navigates back to that page, the pop up returns. I can think of a few ways around this, but is there a "proper" way? Can you trigger a popup off of a variable returned from a service? Thank you!
