When I open a Lr file in Ps by selecting Edit In, the file often opens in a copy of Ps on a backup drive rather than the main copy on my boot drive. Although this issue is new to me in the last 10 days or so, a Google search shows it has been a known issue for years. I haven't found a fix. A Lr plugin called Photoshop Picker was suggested as a way to specify which copy of Ps you want to launch from within Lr, but I can't find that plugin on the web or using Adobe's plugin manager.
I have had short-term fixes by designating the correct copy of Ps as my Additional External Editor in Lr preferences. But this does not allow other functionality such as Open as a Smart Object.
Thoughts?
