Hi, I got some expression in Reduce as result of calculations. When I try to scroll window Reduce with result to view all members of result I see next picture. Some brackets, indexes disappears. After scrolling up and down I see among sum's members message malformed expression And in the console appears strings like Unrecognized keyword "\righ" "{" expected after keyword "\mathrm" "}" not found and etc. If I repeat up and down scrolling many times (~5) Reduce exit with messages FXTerminal::replaceStyledText: bad argument range. emergency stop (this my translation from Russian) Previous version Reduce in Gentoo has not that mistake. Current version works fine with option off nat. Below is program with that behaviour: off lower$ load_package noncom2; operator a2,a2c; noncom a2,a2; noncom a2c,a2c; noncom a2,a2c; operator U,UC,V,VC, Delta, InvDelta; H := 2*B*a2(j1)*Delta(i1  j2)*V(i,j2)*VC(i,j1)  2*B*a2(j2)* Delta(i1  j1)*U(i,j2)*UC(i,j1) + 2*B*a2(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1)* InvDelta(i1  j2)*InvDelta(j1  j2)*U(i,j2)*VC(i,j1)  2*B*a2(j2)*a2(j1)*a2(i1)* InvDelta(j1  j2)*U(i,j2)*VC(i,j1) + 2*B*a2c(j1)*Delta(i1  j2)*InvDelta(j1  j2 )*UC(i,j1)*V(i,j2)  2*B*a2c(j1)*a2(j2)*a2(i1)*InvDelta(i1  j2)*U(i,j2)*UC(i,j1 ) + 2*B*a2c(j1)*a2(j2)*a2(i1)*U(i,j2)*UC(i,j1)  2*B*a2c(j2)*Delta(i1  j1)* InvDelta(j1  j2)*UC(i,j1)*V(i,j2) + 2*B*a2c(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1) *V(i,j2)*VC(i,j1)  2*B*a2c(j2)*a2(j1)*a2(i1)*V(i,j2)*VC(i,j1)  J1*a2(j1)*Delta (i1  j2)*V(i + 1,j2)*VC(i,j1)  J1*a2(j1)*Delta(i1  j2)*V(i,j2)*VC(i + 1,j1) + J1*a2(j2)*Delta(i1  j1)*U(i + 1,j2)*UC(i,j1) + J1*a2(j2)*Delta(i1  j1)*U(i,j2 )*UC(i + 1,j1)  J1*a2(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1)*InvDelta(i1  j2)* InvDelta(j1  j2)*U(i + 1,j2)*VC(i,j1)  J1*a2(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1)*InvDelta(i1  j2)*InvDelta(j1  j2)*U(i,j2)*VC(i + 1,j1) + J1*a2(j2)*a2(j1)* a2(i1)*InvDelta(j1  j2)*U(i + 1,j2)*VC(i,j1) + J1*a2(j2)*a2(j1)*a2(i1)*InvDelta (j1  j2)*U(i,j2)*VC(i + 1,j1)  J1*a2c(j1)*Delta(i1  j2)*InvDelta(j1  j2)*UC( i + 1,j1)*V(i,j2)  J1*a2c(j1)*Delta(i1  j2)*InvDelta(j1  j2)*UC(i,j1)*V(i + 1 ,j2) + J1*a2c(j1)*a2(j2)*a2(i1)*InvDelta(i1  j2)*U(i + 1,j2)*UC(i,j1) + J1*a2c( j1)*a2(j2)*a2(i1)*InvDelta(i1  j2)*U(i,j2)*UC(i + 1,j1)  J1*a2c(j1)*a2(j2)*a2( i1)*U(i + 1,j2)*UC(i,j1)  J1*a2c(j1)*a2(j2)*a2(i1)*U(i,j2)*UC(i + 1,j1) + J1* a2c(j2)*Delta(i1  j1)*InvDelta(j1  j2)*UC(i + 1,j1)*V(i,j2) + J1*a2c(j2)*Delta (i1  j1)*InvDelta(j1  j2)*UC(i,j1)*V(i + 1,j2)  J1*a2c(j2)*a2(j1)*a2(i1)* InvDelta(i1  j1)*V(i + 1,j2)*VC(i,j1)  J1*a2c(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1)*V(i,j2)*VC(i + 1,j1) + J1*a2c(j2)*a2(j1)*a2(i1)*V(i + 1,j2)*VC(i,j1) + J1* a2c(j2)*a2(j1)*a2(i1)*V(i,j2)*VC(i + 1,j1) + J2*a2(j1)*Delta(i1  j2)*U(i + 1,j1 )*V(i,j2)  J2*a2(j1)*Delta(i1  j2)*UC(i,j2)*VC(i + 1,j1)  J2*a2(j2)*Delta(i1  j1)*U(i,j2)*V(i + 1,j1) + J2*a2(j2)*Delta(i1  j1)*UC(i + 1,j1)*VC(i,j2) + J2* a2(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1)*InvDelta(i1  j2)*InvDelta(j1  j2)*U(i, j2)*U(i + 1,j1)  J2*a2(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1)*InvDelta(i1  j2)* InvDelta(j1  j2)*VC(i,j2)*VC(i + 1,j1)  J2*a2(j2)*a2(j1)*a2(i1)*InvDelta(j1  j2)*U(i,j2)*U(i + 1,j1) + J2*a2(j2)*a2(j1)*a2(i1)*InvDelta(j1  j2)*VC(i,j2)*VC( i + 1,j1)  J2*a2c(j1)*Delta(i1  j2)*InvDelta(j1  j2)*UC(i,j2)*UC(i + 1,j1) + J2*a2c(j1)*Delta(i1  j2)*InvDelta(j1  j2)*V(i,j2)*V(i + 1,j1)  J2*a2c(j1)*a2( j2)*a2(i1)*InvDelta(i1  j2)*U(i,j2)*V(i + 1,j1) + J2*a2c(j1)*a2(j2)*a2(i1)* InvDelta(i1  j2)*UC(i + 1,j1)*VC(i,j2) + J2*a2c(j1)*a2(j2)*a2(i1)*U(i,j2)*V(i + 1,j1)  J2*a2c(j1)*a2(j2)*a2(i1)*UC(i + 1,j1)*VC(i,j2) + J2*a2c(j2)*Delta(i1  j1)*InvDelta(j1  j2)*UC(i,j2)*UC(i + 1,j1)  J2*a2c(j2)*Delta(i1  j1)*InvDelta (j1  j2)*V(i,j2)*V(i + 1,j1) + J2*a2c(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1)*U(i + 1,j1)*V(i,j2)  J2*a2c(j2)*a2(j1)*a2(i1)*InvDelta(i1  j1)*UC(i,j2)*VC(i + 1,j1 )  J2*a2c(j2)*a2(j1)*a2(i1)*U(i + 1,j1)*V(i,j2) + J2*a2c(j2)*a2(j1)*a2(i1)*UC(i ,j2)*VC(i + 1,j1); end; Best regards, Petrov Alexander.
