Just an update: Unfortunately I spoke too soon. Seems like it didn't really change anything afterall. I will send my config to support as suggested, but just a few more clues:
- After a slow startup, PowerArchiver will start very quickly at subsequent starts, BUT....
- This only lasts for an unexplained amount of time. For example the next day (no reboot!) I'll have the exact same problem again.
- When the startup is slow, it's close to 15 seconds before PowerArchiver shows up. This happens no matter how I bring up the UI (ex. right-click on a file and choose Extract Here... 15 seconds before it starts)
