Ridiculous number of file handles in Keyscape

Found the Culprit - it’s Keyscape. Is this normal? Anyone else see this? This causes keyscape to take a REALLY long time to load - and when loading, it blocks Cantabile till all is loaded - which is strange to me as most plugins (like Kontakt) return when they’ve loaded the preview samples - and then load everything else in the background.

Anybody got any experience with Keyscape loading?
