Hi Perlers,

I've run into a bug in Curses::UI that means I have to abandon it if I can't find a solution. I've got an entry mask and I'm enforcing some rules, such as that particular fields may not be left empty. I'm using "-onblur" on TextEntry widgets to call a function which checks validity, and if the content is invalid:
1) calls "$root->dialog()" to notify the user and
2) sets focus back to the widget that was just left.

This works fine if the following widget is another TextEntry, but if the next is a Popupmenu widget, the Popupmenu widget gets highlighted, while the actual focus is still in the TextEntry widget, but with no cursor. This is totally misleading for a user and unacceptable.

The mainainer doesn't return emails. Does anyone have any suggestions? I include a reproducer below.

cheers,
