P: Doesn't respect assigned space; Photoshop does (OS X 10.11.4; LR 2015.5 release)

[eoren1]

I run Photoshop and LR CC on a 27" 5k iMac with a second monitor (Dell UltraSharp UP2516D via display port).

Both LR and Photoshop are assigned to 'Desktop on Display 2'.

When launched, Photoshop opens on the secondary monitor.
Lightroom always launches on the main screen.

This has occurred on OS X 10.11.3 and now 10.11.4.

Just tried a re-install of the OS due to an issue with my APC UPS supply not showing and it fixed that issue but not this one.  

Spoke to Apple support about the above and they could not find any info on their end as to why this behavior might be happening.

Just updated LR (release 2015.5) but no change in the behavior.

Any suggestions?  I've got to believe it's an issue with LR since Photoshop behaves correctly.

I am also able to reproduce this problem, and I have reported the issue to the Lightroom engineers.  However, the problem seems to have an easy workaround: put Lightroom into "Full Screen with Menu Bar" screen mode.  Do this by going to Window>Screen Mode>Full Screen with Menu Bar.  After that, Lightroom launches on the correct screen.  Let me know if that doesn't work for you.

Thanks,
Ben

Thanks Ben!

Not only does that work but it's a better mode than what I had been using.

Appreciate it.

So it turns out that Full Screen mode does not respect the assigned space after a restart.  Also seems to open on main monitor periodically at other times.

I'm sorry to hear that!  Thanks for following up, I've added this information to the bug report.

Hi Ben,
Any updates on this? I just saw the LR had a bug fix update but the behavior with a second window hasn't changed.
Thanks!

Looking at the notes in the bug report, it looks like a fix was put in for the previous release, and was then pulled because it broke something else.  It's never easy, is it?  🙂  Looks like a fix is still planned for an upcoming release.

Thanks Ben.  Really appreciate the update.  Figures that would break something else...
