4. _K_n_o_w_n__P_r_o_b_l_e_m_s__a_n_d__W_o_r_k_a_r_o_u_n_d_s
This chapter lists the major known problems in IRIS
Annotator 1.1.2
+o The Annotator file format has changed. Although
Annotator 1.1.2 can read both the new and the old
format, Annotator 1.0 cannot read the new 1.1.2 file
format. To work around this, you can convert the
Annotator 1.1.2 file using the _i_v_d_o_w_n_g_r_a_d_e utility
program, shipped with the Open Inventor 2.1 (or 2.1.1,
2.1.2) Execution Environment. Note that _i_v_d_o_w_n_g_r_a_d_e
produces an ASCII file, which is much larger than the
original Annotator binary file.
+o The Annotator User's Guide has not been updated to
reflect the new items in the ``Notes'' menu. Nor has it
been updated to document the change from MedaiMail to
Netscape mail.
+o Some model data may not be transferred correctly when
you mail an annotated scene, or when you copy a model
from one Annotator session and paste it into another
(or into another application). The problem occurs when
the model refers to other files through SoFile nodes,
or SoTexture2 nodes; the receiver of the mail, or the
application doing the paste, may not find the
referenced files. To work around this you can expand
the model file to include all the data inline before
reading it into IRIS Annotator. Use 'ivcat -tfb
oldmodel > newmodel' to expand the model.
+o Sometimes you cannot pick objects constructed from
NURBS surfaces. When that happens, try moving the
cursor a little, or adjust the view slightly, before
trying again.
+o Sometimes when you switch to the orthographic camera in
the viewer, you can no longer pick objects, or attach
arrow markers to objects. When this happens, switch to
the perspective camera again (using the bottom icon in
the icon column on the right hand side of the Annotator
main window).
+o If you hit "Cancel" in the capture tool while recording
a Movie note, the movie data will be deleted, but the
note icon remains attached to the marker. However, if
you try to play the note, it won't find the data.
Remove the icon by clicking on it, and then selecting
``Delete'' in the Edit menu.

+o The first time you run Annotator, when you start the
capture tool to create a new note, capture may not
start in the correct mode, or the capture window may
flash briefly, then disappear. If it starts in the
wrong mode, you can fix the problem by selecting the
correct mode using the button pop-up menu in the lower,
left corner of the capture window. If the capture
window flashes, then disappears, you can fix the
problem by running capture once from the desktop.
(Select ``Find->Media Tools'' from the toolchest, then
double click on the capture icon. When the capture
window appears, select ``Quit'' from the ``Actions''
menu).
+o If the Texture Editor is open when you iconify the
Annotator window, the selected object will no longer be
visible in the Texture Editor when you de-iconify the
window. To get the object back into the Texture
Editor's viewer, close the Texture Editor, and then
re-open it.
+o When you change the material of an object (using the
Material Palette or Editor) while the Texture Editor is
open, the material change is not always reflected in
the Texture Editor's viewer. When this happens,
deselect the object in the main Annotator window, and
then re-select it. Alternatively, you can close the
Texture Editor, and then re-open it.
+o When you undo/redo a texture mapping operation, the
operation is undone/redone in the main Annotator
window, but not in the Texture Editor's viewer. To see
the change also in the Texture Editor, deselect the
object in the main Annotator window, and then re-select
it. Alternatively, you can close the Texture Editor,
and then re-open it.
+o The -r and -R options require an absolute pathname for
the input file. For example, the following sequence of
commands will cause an Annotator error message to pop
up indicating that the file Pear.iv cannot be found:
% annotator
% cd /usr/share/data/models
% annotator -r Pear.iv
However, the following sequence will correctly insert
the Pear.iv model into the Annotator scene:
% annotator
% annotator -r /usr/share/data/models/Pear.iv

+o Playing Movie notes may alter the hardware audio
sampling rate. Consequently, any Sound notes that
follow may not sound right.
+o Cut or Copy of existing multimedia notes, sometimes
gets a bus error and core dump.
