Re: Bug of Units-package in combination with DynamicModule

Thanks a lot, Maxim. Initialization :> AbortProtect[Needs["Units`"]]
indeed solves my problem completely. SynchronousInitialization ->
False works only partially as other dynamic objects inside the
DynamicModule are already updated before initialization of the
DynamicModule is complete.

Best regards,
Hannes Kessler
