I recently installed Juno via JuliaPro188.8.131.52 (operating system is Pop!_OS 19.04). If I try to rearrange any of the panes, the IDE hangs and I have to force quit to shut it down. This also seems to happen if I try and drag and drop the files in the project pane.
IIRC someone told me about this during JuliaCon, and I think this is fixed in newer Atom versions.
A new JuliaPro version should be out relatively soon, so I’d recommend upgrading once that’s available. JuliaPro 1.2 is out, so give that a shot.
That did it. Thanks for the quick feedback!
