Always on the first (fresh) launch of Dorico - not double-clicking a project, just the app itself. It just sits and waits for a good minute/90 secs, at that screen… After it opens, I can happily work, save, close out of Dorico, then re-launch (the app only) and this time it is very quick to open (less than ten seconds).
I’ve kept tolerating this (since at least v3.x.x); but just now, got annoyed and decided to post…! Can I send a diagnostic to you @Ulf to examine via a PM please.?
No problems with other audio apps (Cubase, WaveLab, Studio One, etc…)
