IIRC the problem was caused by a function called GetCPUSpeed, in VCL versions < 1.9 the algorithm
did a division by 0. Although I never used this function explicitly, it somehow got into my
application, maybe it was called internally be some other JEDI function.
Back then, I searched for the function and disabled it, but I think the developers have since fixed
the function. Current version of the VCL is 1.95 or 1.96.
