Question: Recursion error when applying "allvalues" to "RoofOf"

Hello everybody, I'm trying to apply the command allvalues to the output of solve( x^2=cos(x^2), x ): RootOf(_Z^2-RootOf(_Z-cos(_Z)), label = _L4) but when I enter: allvalues(%) I get the following error message under Windows XP SP2: Error, (in @) too many levels of recursion Does anybody know what's going on? Many thanks in advance, Ruben
