Known Bugs¶

• (New for v1.5) Resuming image acquisition from Square Targeting after Leginon
  restart may cause reacquisition of children of the unfinished target list on 32-bit
  Linux machine.

Dictionary ordering problem of MySQL query, No temporary solution.

• (New for v1.5) DataAccessError may show up when a user starts new application if
  default is loaded to an existing database.

Temporary solution: See <link linkend="bad_default_reference">Operation Trouble
Shooting</link> on the subject.

• (New for 1.3) Navigator multiple move option does not work properly in MSI imaging
  sequence with image shift as the move type.

Temporary solution: Always use preset manager when move type is image shift.

• Web viewer may not display all targets on the parent image since target is
  transferred to a different version.

No temporary solution.

• Kill Application may not kill all process cleanly and may cause problem in
  connecting to TEM or camera when a new application is reloaded.

Temporary solution: Close leginon and clients and restart.

• Simulate Target use the current image shift as the target shift on top of its preset
  shift. Therefore, the acquired image may carry an additional image shift if there is an
  offset created from previouis acquisition.

Temporary solution: Always use Presets Manager to send the preset to be used in
simulation first before usinging Simulate Targets tool.

• Some, although fewer, User Notification "processing " icons do not disappear but
  stay pointing up after the node is done.

Temporary solution: None.

• When running on LINUX system, Preset selection in /Presets Manager/Importing Presets
  from Another Session/ add a selection when mouse is left-clicked rather than toggle the
  selection as in convention.

Temporary solution: Hold down to Ctrl key to select and deselect multiple presets.
Shift key still means selecting all between the two clicks.

Note: This problem is caused by some bug in wxPython for LINUX.

• Web 3way Image viewer does not always show in yellow the revised (i.e. after drift
  correction) current target in the parent image.

Temporary solution: None.

• Starting Manual Focus directly by clicking on the tool does not use preset but still
  check for the preset assigned for the focuser node.
