We have a very strange issue when updating the data for a chart in a PowerPoint representation. Unfortunately we cannot easily provide a source-code with a test case, because we only have this issue occurring in one customer environment (it works in our own environments with the exact same data, PowerPoint file and source-code).
What happens is this:

We know that you cannot reproduce this issue without a sample application, but this is currently very difficult to achieve, because it only happens (consistently) in the mentioned customer environment. But maybe you have an idea what is involved in your SetRange method and if you have any idea what could cause the issue (e.g. does it depend on regional settings of the computer when interpreting number formats etc.)?
