I recently published an excel Chart and an excel Sheet to two different webparts within a SharePoint 2010 Team site. The chart and the Sheet both display fine, however when I visit the machine of a colleague and view the chart and sheet, things become interesting. Although both appear fine on my machine, on the machines of others, either only one is showing and the other just cycles as though its going to load or one shows and the other is x'ed out. I've seen this on about 3 different machines now. There supposedly aren't' any network issues currently.
What would cause this and how can I resolve it?
