Description Chris Goldthorpe CLA 2011-09-22 14:42:20 EDT 
+++ This bug was initially created as a clone of Bug #358315 +++

It appears that since 3.7 Forms is disposing of an image it later tries to repaint.
We have a special task editor with an image appearing on-hover. If one hovers once, then submits the editor, immediatelya graphic is disposed exception is thrown. Further investigation showed that the disabled image is getting disposed, but something is triggering a repaint afterwards not checking for disposed widgets.
