            Description

            A few users have point at this but I thin I finally found the cause. When working though a large document there is an eventual slow down and there is a lot of time spent doing garbage collection. As a result of this collection the UI feels really slow.

            I kicked the tires a bit and found that the we are using Softreferences for just about everying, which make it hard for the garbage collector to know what to do.
