Hello,

when loading the FeynCalc package into Mathematica 5, the following
message appears:

TagSet::tagpos: Tag Re in \!\n\(TraditionalForm\`\(\(\(\(\(Re(OPEm)\)\) -
\
\(\(Re(i)\)\)\)\) > 0\)\)\n is too deep for an assigned rule to be found.

and when I try to calculate:

Tr[FourVector[
k1 + k2, \[Mu]] . (GA[\[Alpha]] FourVector[k1, \[Alpha]] +
IdentityMatrix[4] m ). (GA[\[Mu]] f1

        0.5 \[ImaginaryI]/
            m 0.5 \ImaginaryI .
            FourVector[k1 - k2, \[Nu]] f2) . (GS[k1] + IdentityMatrix[4] m)]

the output contains the text:

HighEnergyPhysics`FeynCalc`DiracTrace`Private`spursav

Sincerely,
Cailin Farrell
