BSOD when paning

I use Radiant at home sometimes to review some MRI.
It´s been a while from last time used it.I had v1.9.4...
Today I opend radiant, had to upgrade the license because of the time... loaded a study and I got a beautifull BSOD.
By now it results in this BSOD any time I load any study and try to pan the image. this is repeteable in a 100%.
I ve upgraded to v1.9.16 but didnt help
Im running windows 7 sp1 ultimate 64bits
w/ nvidia 86000GT driver version 340.52 (upgrading to 341.44 by now as this looks related to video)

any help is welcome..

Hi, I made some testing,
newer nvidia driver did not solve the problem.
I did setup a new VirtualBox windows 7 64bits with Radiant viewer.. At firs I thought it was ok but it wasn´t .
It was more permissive but after a few minutes t hanged up again, this time the issue was managed by VB letting me to terminate the virtualbox instance.. and nvidia driver pope up an error warning about openGL 3 crushing.
I disabled 2D and 3D accelerations in VB but this happened again..
I ended up reviewing the studies starting windows in "safe mode" this worked :D..
Ugly !! but radiant works in safe mode best than I thought i would,,,
any way hardware and software incompatibilities were mostly isolated using a fresh virtual machine setup but issue persisted..

Hi TiTo,

Thank you for your reports.
Are you sure that it's not a hardware related problem? Perhaps some obscure memory (main or GPU) errors? (Virtual Box could also hang if a memory error is encountered).
It's been the first time that we received such report (BSOD) since we started developing RadiAnt 5 years ago... Also, during extensive testing we've never encountered a BSOD caused by RadiAnt.
RadiAnt does not use OpenGL, so the OpenGL crashing seems to be unrelated to our software.
I'm afraid that there's not much more we can do other than suggesting to try running RadiAnt on other hardware.

You can also try our latest beta version:

Hi Maciej
well it is really extrange to me to.
I didn´t have any toruble with Radiant before (but I havent used it for a long time)
But I am also a photographer so I use programs like adobe Photoshop or Lightroom that stresses ram and GPU much more than radiant and I dont have a single problem with them...
Crusshing happens with Radiant exclussively and a little after starting viewing images,,
perhaps its not opengl, I saw that report only onece..
trouble with ram would be more random in apearence,
I´ll do some more testings and let you know.
Thanks for the answer, and keep going with radiant as is a veri good piece of work..

Hi TiTo,

Did you try our latest beta version? This build makes use of a new toolkit, we'd appreciate if you check whether your BSODs persist with it.

Yes The latest Beta is still hanging up.
At this time I am pretty sure it is a hardware issue but it is rare how radiant reproduces the BSOD every time in a few seconds when zooming, panning or windowing.
I´ve noticed how much raises CPU usage at those moments.
It is an AMD phenom II 1090T (six cores) running stock.

at least I have in Radiant a really good diagnostic tool. (for my hardware failure ;-) )

The raise in CPU usage during panning/zooming/windowing is normal, as RadiAnt uses available CPU cores to perform this processes. Perhaps you have some problem with the CPU temperature?
