Dear all, the following bug observed is in Mathematica 8.0.4 under Windows:

DynamicModule[{x=\[Infinity]},InputField[Dynamic[x]]]

An error "An unknown box name (DirectedInfinity) was sent as the box form for the expression. Check the format rules for the expression" appears after saving and re-opening the notebook. Does anybody know a workaround until the bug will be fixed in the Mathematica code?

Best regards,
Hannes Kessler
