--- Comment #9 from Pacho Ramos pachoramos1@gmail.com --- I indirectly hit this bug while trying to run GraphPad Prism with wine: https://www.graphpad.com/support/faq/will-you-port-prism-or-instat-to-linux-...
I couldn't save project files due to "missing" IE6 for XML support. I solved it by switching to wine-staging, that solves this bug.
