Problems with thresholding

This is a bug report from Richard Bourgon through Michael Lawrence. It is logged at sourceforge #3299951

Another to add to the queue. Sometimes, the dialog for setting graph thresholds stops working properly. Changes made by typing into the "By Value" box have no effect, although if I grab the slider to the right of the box, I CAN make changes which show up on the graph. There are also weird problems with focus not being indicated properly in the dialog box: highlighting is missing altogether or on some other field, but if I start typing, I'll be able to do data entry in a different field. The console shows

which then alternates with

Both go on and on and on.

No crash though...
