I just installed the 1st Public Beta of macOS Mojave, and there are a few issues that I noticed right off with PanX: 1) only the top half of the icons in the Tool Bar display, 2) when using the Find/Replace routine in the object procedure window in the sidebar, the background is nearly transparent which is very confusing, and 3) line numbering in stand-along procedure windows sometimes overwrites the lines of code. Otherwise, things seem to be good. If other issues develop, I’ll be sure to let you know.
