"Launch View" Button Does Nothing

[portisleft]

I am a first time JBrowse user. I downloaded the program on Mac, launched it, and was playing around to familiarize myself with the UI. I had opened a session looking at a fungal genome, I was able to see the whole genome, toggle on GC content, look at predicted genes, etc. And then I did SOMETHING, I don't know what, and now I am able to launch new sessions and open old ones but I can't see the actual genome. I get a pop-up that prompts me to select a view to launch, and no matter what I choose (linear, circular, spreadsheet, etc), the launch view button does nothing. I have tried restarting the session, opening a new session, restarting JBrowse, I still can't get the 'Launch View' button to work. Anyone else have this issue and know how to solve it?

Hi there, looks like this is likely related to our new feature for 'Workspaces' (https://jbrowse.org/jb2/blog/#new-workspaces-feature-for-tiled-window-management) in the latest version. I will make a bugfix for it asap!

Note that you can toggle off the checkbox in "Tools -> Use workspaces" for now

A fix for this is now released in v4.0.4, thanks again for reporting this! We now do a bunch of automated tests to help catch issues like this
