graphics sometimes crash when trying to view some very large systems (large
proteins, imported from PDB). 2000-04-14 // does this apply anymore???

problems with selection in wireframe models (mm1_mdl). with other rendering
modes selection is ok. 2000-04-14 - PS: selection should work for "front"
items, but it sometimes seems to work with "back" items; this is related to
your OGL/Mesa implementation. if this annoys too much you can take a look
at camera::RenderWindow() and switch it quite easily.

some stability problems when mass-converting PDB->mm2. looks like a memory
leak?!?!?! 2000-05-16 // could not repeat this later anymore...

volume rendering objects are connected to camera -> if a camera with a VR-
object is closed, there will be problems!!! Object handling in general is not
yet ready -> this (and some other related) bug(s) must be dealt with later.

in the GNOME version, all MDI mode changes and drag/drop operations that move
a tree/list view into another window, will cause problems to tree/list views.
the subtrees will lose their expand-buttons, and tree/list view operations
start crashing... ADVICE: do not move tree/list views; use the notebook mode,
and drag/drop graphics views instead of tree/list views. 2000-12-22 TH
