Synchronous operation causes CBP Launcher to "hang" while loading or performing I/O

[MHLoppy]

Known issue. Unfortunately resolving it would require rewriting significant amounts of code, so it's just about at the very bottom of the priority list next to other things that are sadly unlikely to be a good use of development time.

I spent a day getting very close to solving this without a significant rewrite, but it seems the way the skins have been implemented simply doesn't quite allow for an easy conversion to fully async code.
