Hello,

We are experiencing the following error on some of our machines: kernel: tumorsim_1.2_li[25155] trap invalid opcode ip:fa0ef6 sp:7fffffffbe10 error:0 in tumorsim_1.2_linux64[400000+fce000]
Only on 1 machine it seems to run correctly.  That machine does have newer hardware, but all the other machines have never had any problems so far.  Is there any way to know what exactly is going wrong?  We had exactly the same error with Beta 1.

If more information is needed, please do not hesitate to ask.

Kind regards,
Herman

Can you try using the 1.2.1 beta1 binary that was just released?
