I am getting an alert in Flash Builder while I am in the process of upgrading my application from 3.6 to 4.5.1. The alert is titled "Design Mode Preloading" and includes the following text:
"Preparing the design mode for this MXML is taking longer than usual, likely due to the complexity of the layout..." Then I am asked whether I want to continue the preloading.
I did not get this alert in the same Flash Builder instance when building my application with SDK 3.6. As such, I am uncertain if this issue is a product of Flash Builder or the SDK.
Has anyone faced this same issue? If so, were you able to resolve it, and how?
Thanks as always!
