I added nanomanager.update_uis(src) to the cryo.dm Topic(). This method updates all UIs attached to the (src) object.Fixed issue with Nano UI windows taking seconds to load.

Removed user << browse_rsc() entries as they caused the delay. New assets (stylesheets, scripts, templates and images) have to be added to the client's send_resources proc or they will not exist on the client.
