[Gambas-user] ComboBox Error when ComboBox.Remove("1") / possible bug in gb.gtk?

[Nicolas Koch]

I am in Gambas 2.9

And even if I do ComboBox.List = Dir(sPath)  hidden folders show.  I
was trying to hide those and ComboBox1.Remove("1") was the only way I
could find that works.  It works but spits out error as I said.
