Dialog windows sometimes not doing anything on v1.1.11

[Vexatos]

The changes introduced in PR #607 seem to cause issues when showing dialog boxes sometimes, at least on Windows. Setting GTK_AUTO_IDLE to false fixes it, confirming that this PR is the culprit.

We don't have much information to present unfortunately, but in some situations, opening a dialog box such as ask_dialog shortly after using Gtk opens a completely unresponsive window. It's not possible to interact with any buttons in the window, including the X button in the window bar. In our tests, adding a simple sleep(0) or println() in front of the ask_dialog is already enough to fix it, so we don't really know why this could happen.

Thanks. I'm looking into this

I don't have access to a windows machine and I can't reproduce this on ubuntu by just doing

julia> begin
           using Gtk
           ask_dialog("hello")
       end

@Vexatos would you mind dev-ing Gtk and trying to add a yield() between line 41 and 42 here?

Gtk.jl/src/base.jl

Line 41 in cea01eb

end

If that doesn't work try between 40 and 41.

Sorry for the breakage!

Putting a yield() after the signal_connect block does indeed appear to reliably fix the issue.
