When running on Windows, if you load up more than one video of any type, DRS hangs regularly. This makes it completely unusable.

This occurs on my office machine, also on Ben B's.

To reproduce quickly - load up two videos, then click the title bar of one, then the other title bar, to repeatedly switch between the two windows.

In actual use, it happens roughly 10% of times you switch between windows. A similar hang also happens about 10% of times when you open an analysis that has multiple videos in.

The UI thread is hanging in Quicktime for Java, in quicktime.app.view.QTJavaAWTCanvas.addNotify, which gets called from something with the super.setSelected() call in AWTQTJPlayer::setSelected()

There is also a "Taskable.tasker" thread that is listed in the debugger as "waiting in a monitor"

It is some kind of deadlock - I suspect someone has done something naughty with quicktime / swing somewhere, but I can't dig it out.

    The problem seems to be significantly worse with Java 1.5. It still crashes occasionally (say 2%), but is usable with Java 1.6. Hence the downgrade of priority - we'll take a look when we can.
