One of the biggest beef’s I have with the BizTalk mapper (other than functiods in general) is the ‘feature’ where, for sale when you click on a source node, it will ‘highlight all of the links and center the destination to show you the links.
For small maps, this is ‘hardly’ noticeable.
However, for maps that are large, and the same input node is used in multiple destination nodes, it becomes hair pulling-ly frustrating.
To disable this, in Visual Studio go to Tools –> Options –> BizTalk Mapper and uncheck the two default checks.
You then need to restart Visual Studio (perhaps just close the currently opened Maps) for this to finally not scroll.
