bugs in Mastodon launcher

[xulman]

Hi,

in the latest Fiji and Mastodon update site content (as of 13 March 2024):

• the Launcher dialog becomes "nothing-available-to-click" (all GUI elements are disabled, all grayed-out) after canceling the open project dialog: open Mastodon project -> Open another project -> Cancel

• new project from URL does nothing

True! The 1st bug is real.
The 2nd one is not a bug :) We are waiting for Ko to finish the new support for remote datasets, and it is still broken in beta 29.
