[Developers] Issues Release 3

[Urs Boeniger]

Dear developers,

I would like to mention a two issues I am facing while upgrading to 
release 3.x.

1. It seems like there is a problem related to OpenGL shading also with 
compatible graphic cards. Using the OpenGL shading enabled it looks like 
once adding a new line (Inline/Crossline/Timeslice)/volume and adding 
and selecting a new attribute the resolution drop down menu gets 
disabled and cannot be used anymore. While one the otherhand adding a 
new line and then changing the resolution first before selecting/loading 
a new attribute the resolution drop-down menu stays enabled and 
selectable for that line always. If one disables the OpenGL shading 
everything works as normal.

2. It seems like there was a change in the position definition upgrading 
to release 3.0. In order to define the elements position in volume 
definition one was able to type a 0 for the minimum value and the 
appropriate minimal values where entered and similarly if you entered 
for example 99999 into the maximum field and you line would only range 
to the index 150, 99999 would have been set to 150 automatically. Since 
release 3 the unfeasible range values are always set to the minimum. Did 
that change on purpose? It previously described method was just a quick 
way in getting the full 3d volume without entering the correct range 
dimensions.

I think these two changes might have been unintentional and I would like 
to know if other experience them in a similar way.

Sincerely,
Urs Böniger
