Hi there,

If you try to set a sub-style using a part marker it doesn't work. Left-click a part marker. Click define substyle. Nothing happens - the style picker is not launched.

Does anyone know how to fix this?

Welcome to the forum. I am positive this will be sorted out. What OS are on? What styles are you trying? It helps if you list the steps used to cause the crash
