load(mnewton);
d1:5;d2:6;x:10;y:4;
mnewton([x=d1*cos(a)+d2*cos(a-b),y=d1*sin(a)+d2*sin(a-b)],[a,b],[0.1,0.1]);
resulted in an endless column of blank %o:s, just like 'collectterms' in a previous issue. It worked just fine in xMaxima and older wxMaxima 7.5
Forwarding this report to Andrej V since the problem is specific to wxMaxima, which is a separate project with its own bug tracker. Therefore I'm closing this report. Thanks for taking the time to report this bug.
Fixed (I hope) by r1.53 src/mload.lisp.
Can someone with a Windows build environment please try it.
The problem is fixed in cvs (checked on windows with xmaxima and wxmaxima).
