Hi,
Based on my understanding of your description, it seems you have a Module that uses a style contained in its own App.xaml file. If this is the case, the problem you are experiencing could be related to a known issue when defining resource dictionaries inside Modules in a Prism & Silverlight application. You can find more information about this known issue, as well as possible workarounds for it, in the following article:
On the other hand, if this is not related to the problem you are experiencing, it would be helpful if you could provide us with more information about where the style is being defined, where the view is and how the view is using the style, so that we can help you further with this.
I hope this helps,
