KNOWN PROBLEMS IN V.2_5beta2
****************************************

* [2003] The generation of a GIF file from a VisiPlot in OT is slower in Java1.4
  compared with Java 1.1.8. This issue has not been investigated.

* [2036] When running Java 1.4 applications on Solaris, and displaying on Linux,
  certain window managers (Gnome and KDE are known) result in the delete 
  (DEL) and backspace keys not working.

  This is a known bug and will be investigated when information is 
  available as to how many user are affected by the bug. (i.e. under what
  cercumstances the problem occurs).

  Workaround: ctrl-h works as a work around.

* [1985] Combo Boxes which display the drop-down list outside of the
  window frame will be displayed behind the main window frame when moving
  the drop-down list scroll bar. This occurs on some CDE (dtwm) sessions.

  Work around: run the command dtstyle (/usr/dt/bin/dtstyle) ,
  select "Window", and ensure the option: "Allow Primary Windows On Top"
  is NOT checked.

  Explanation:

  This is a reported Java1.4 bug (#4781582), which is "in progress".

  When a combo box displays out side of the main window frame,
  it is represented with a "heavy weight" component (i.e. a window,
  managed by the window manager).

  This heavy weight window, in combination with the window manager style
  setting allowing a parent to be displayed in front of the child,
  means the combo box list dropdown will fall behind the main window.

* [xxx] Visiplots: grouping identical OBs for display may result in a 
  long list of OB ids. If this list is long, it will extend off
  the edge of a printed page or mis-shape the plot. The list needs
  to be re-organized to be displayed over multiple lines.

* [xxx] Visiplots: while the display and printing of plots has been
  optimized for minimal graphic memory usage, the saving of plots
  to GIF files still uses a considerable amount of memory and _may_
  present problems for some Xterminal environments. When an Xterminal
  is running on less than 1 Meg memory, the behaviour of graphical
  applications may become unpredictable.

* [1114] Breaking a long query in the Repository Browser (several
  hundred OBs) might sometimes cause problems. We're investigating to
  understand why.

* [1147] Foreign key constraint violation? 
  Could not be reproduced.

* [1167] Append new OB to a queue: nothing happens 
  Could not be reproduced.

* [1169] NullPointerException generated by NextObsBlocks 
  Could not be reproduced.
