Lightroon Classic trouble with the "select a source" window constantly and randomly popping up.

Lightroon Classic trouble with the "select a source" window constantly and randomly popping up.

This happens randomly and very frequently when:

• I move mouse across the page
• I chose the crop tool when in Develop module
• Or I am simply working in LR

All updates complete and running LR Classic 11.5 (this has been happening for months with previous versions as well)

When I close LR I get this message even though I have previously closed the “select a source” window

My computer specs:

Windows 10 PC with

This is becoming so frustrating. I appreciate any help.

Check your Preferences in the 'General' tab-

Be sure this one is NOT checked.

It may be that LrC is randomly detecting an external drive or a USB stick, and so initialising the Import dialog.

Thanks. The box was checked so I unchecked it and will hope this is the solution. appreciate your quick response. 

If by chance this doesn't solve the problem how would I continue the thread, will it remain active?

"It may be that LrC is randomly detecting an external drive or a USB stick, and so initialising the Import dialog."

There have been two causes of these symptoms reported here over the years:

- A loose hardware connection/cable causes Windows to repeatedly detect the drive and report it to LR as a newly added volume.

- Some obscure Windows utility (perhaps an enterprise utility) would temporarily create a network drive, check something, and then delete the drive immediately, and LR would get the report of a newly added volume.

Unchecking the option suggested by Rob could make the annoying LR behavior go away, but it won't address the underlying issue.  You could keep Windows File Explorer open and try to see if you see a drive letter appear and disappear fleetingly.
