Issue 1828 – Path on Address bar of Explorer interface cannot be submitted

I'm sending an email with a development version of WinSCP to the address @zorlon has used to register on this forum.

Same here, I can no longer paste paths into the address bar, when I click Enter I get a Windows error sound and nothing happens. Makes reaching deep paths very uncomfortable..

Thanks for looking into this

Hello!

I often use the address bar to navigation (in the Explorer style). And after updating to 5.17 I insert the path into the address bar and hit Enter, but nothing happens. Navigating via address bar doesn't work.
