RiverWare 5.1 [Feb 2009]: New Qt4 "Graphics View" Workspace Fix:
Fix to aborting a selected Object Icon Move by hitting the ESC key.

The first implementation ran into a Qt 4.3.3 bug related to cancelling the QGraphicsItem Mouse Grab. More about this problem:

• Post on the QtCentre Blog
• Initial post text

The new implementation overrides the effect of a mouse drag-move after the ESC key is clicked, until the mouse button is released (i.e. without cancelling the grab). It replaces the position value of icon position-change events with the pre-drag-move position.
