Description
A forum user first commented on memory exceptions with the viewer RI and I as able to the verify the problem with a heap of 64m and a large file. I'll put in more detail below but there are few spots where we where not unregistered , keyboard, focus and mouse events.
Closing issue. The Viewer RI can now open and close large documents with a limited heap size without any heap issues. The profiler results also look promising with only one instance of a Document kept around between file opens.
