#21 After-build hang

[Jeff Keegan]

Using the 20100806 build, after a print the host becomes unresponsive (at least for me). The following things happen:

1) The high pitched whine from the extruder motor stops (ok)
2) The status bar saying how long until the build is done never completes
3) The time until completion continues to adjust, changing to further and further in the future, even though the build is done
4) You can change tabs, but if you then try to move the Y axis by clicking that row's ">" button (for instance), nothing happens on the RepRap, and the button stays "pushed in" (colored dark blue). At this point the entire UI is frozen, and you can't even edit the text fields for X Y and Z positions on that tab.
