This error is being raised using my mouse to scroll to tabs left of current tab. I scroll (down) I believe inside the Tabs.
(lazarus:9726): Gtk-CRITICAL **: gtk_widget_is_ancestor: assertion `ancestor != NULL' failed Finally, most everything checks out working BUT the following problem: I have nested tab controls and I'm noticing various GroupBoxes that are set visible=false but are being displayed at runtime even though it should not. cbClusters_ClusterInfo.Visible=false but you can see it through the GUI (See attachment) This is a problem b/c the groupbox inside nested (PageControl/TTabSheet) is part of logic that does not make sense until GUI is put into edit mode. Can you find the culprit w/o back-trace or errors being thrown for this particular problem? If not, how do we get this problem fixed?
