     Type:  defect           |      Status:  new           
 Priority:  blocker          |   Milestone:  Never Assigned
Component:  browse-activity  |     Version:  Build 650     
 Keywords:  Browse Record    |    Verified:  0             
 Blocking:                   |   Blockedby:

 To induce this bug in build 650:
  1) record video in Record[[br]]
  2) in Journal, open video object that was just created in Record[[br]]
  3) instead of playing the video, Browse commences to "download" a copy of
 the video, writing a new identically-sized file to the datastore (this
 seems to be a bug, documented in #5687)[[br]]
  4) toggle between the Sugar home and Browse using the 'zoom' buttons.
 Graphics from the homepage persist in the Browse window below the download
 dialog.

 This redraw problem also happens in the Browse-download case described in
 #5665 (description line item number 3) in toggling between the home-page
 and the activity.

 Although the examples used here to reproduce this bug are bugs themselves,
 this issue is a bug that should be resolved independently from those bug
 fixes. It ''is'' reasonable behavior for a new Browse instance to be
 opened with a URL that may induce a download instead of opening a new
 page, and such behavior is broken by this bug.

 This bug is very confusing (and exasperating) to users, especially novice
 users, who don't know what's going on when seeing UI elements that don't
 respond.  This bug gives users the sense that the system is broken or
 unusable.
