Hi---

All of my figures that use MP boxes are now failing. It loo= ks like "boxjoin" (from the MP "boxes" macros) is not b= eing recognized. Also, apparently unrelated, I wonder if the comparison in = "boxes.mp" is correct as it appears that lmtx loads "mp-xbox= .mpiv" instead of "mp-xbox.mpxl". Here is some log output and a (mostly= ) MWE.

Thanks for any suggestions,
