after using "continue simulation" scene ist not respnsive any longer

[useruser]

...unfortunately the problem still exists with beta2.
with another project, including an animated windeffector, fumefx quits simulating after a couple of frames. i will post the projectfile a bit later.
what i recognize until now: the fumefx-simulation works without any trouble with higher spacing values. for exampke:
spacing value „2 cm“ works fine, but when i decrease the grid-resolution down to „0,5 cm“ fumefx shows the same behavoir as in beta1
please support, can you confirm that?
thanks in advance!
