'Goto' dialog breaks keyboard support?

[fire-eggs]

After using the 'goto' dialog to view a different image in the list, all keyboard actions stop working. I.e. it is no longer possible to view "next image" with the right-arrow, page-down, etc.

This issue is intermittent. Sometimes happens immediately, sometimes multiple uses of the 'goto' dialog is required.

Observed multiple times on KDE, possibly not on Linux Mint Cinnamon.

This is not a same breaking issue, but strange operation looks similar -
I'm trying to make some application with Wayland today, and there are a lot of bugs.
I think many Linux xservers are lost key handling when in many kinds of cases ( Even Windows too ... )
Did you implement to handle key with FLTK ?

I've not confirmed yet, but I think my issue is:

1. Dismiss the dialog by clicking 'OK' or the close button: keys behavior is fine.
2. Dismiss the dialog by hitting the 'Enter' key (default button): keys stop working.

I have to check to see if I have a key handler at the top / application level, which might be part of the problem.
