Retested with a clean 4503 release image,
which I created from a clean copy of a 4426 image, installing all 
updates and saving it as a new release:

'-4 sqrt' displays the menu and If I choose not to load the Complex 
package it pops up a debugger. If I choose proceed in the debugger,
it answers an instance of the NegativePowerError
exception.

Choosing the same menu option with '-4.0 sqrt' directly answers a NaN.

Juan, I presume that is not the behavior you intended. Please tell me, 
if I should test with a 32-bit image, that only has boxed floats.


HTH,
