%%%That's it, a weird bug. I realized that if I try to bake a fluid simulation, it will bake only the first frame and then stop. Oddly, baking will work fine if the Node Editor is closed or if "Use Nodes" is not activated.

I attached a simple fluid simulation file. If you try to bake the fluid simulation, it will stop at the first frame. If you uncheck "Use Nodes" or remove the "Node Editor" from the interface (joining areas or changing it in the Editor Type button), baking will work normally. It took me a long time to realize this, and I'm sure that many people have this problem and don't know why (after Googling around).

This bug was tested only in Blender 2.64 r51026, but I'm sure it exists on previous Blender versions, although I've seen it only in Windows.

%%%Extra info: I've seen this bug on both 32 and 64 bit versions of Blender for Windows.%%%

%%%Edit: Mea culpa... in Blender 64 it crashes, in Blender 32 it simply bakes first frame only.%%%

%%%I found the bug - very bad one, in Blender 2.5 for long too.

The bug was in code to get a WindowManager thread job - it was giving the running fluid job to the compositer... tsk tsk%%%
