while my first steps with Stream i got the following problem:

Modifying the 'Copy-Kernel' from the samples from 'float' to 'short' works, to 'short2' crashes constantly (-> Program hangs, -> GPU-Recover tries to get GPU back up). After 3-4 crashes that way all GPU acceleration including 2D-Desktop acceleration vanishes until system reboot.


kernel void copy(short i<>, out short o<>
    o = i;


kernel void copy(short2 i<>, out short2 o<>
    o = i;

Any ideas?
