Strange behaviour for ComboBox and TabFolder
created standard window(parent TabFolder) with widgets
inside code with widgets, ran ProgressMonitorDialog
.... And Error.
Attention!!!
1.If Change TabFolder to CTabFolder to That's all right!!!!
2. If change Combo to other widget (for example Label) that's all right too and with TabFolder.
I don't understand where is mistake. Combination Combo and TabFolder doesn't work

I see link to my old post. I don't exactly remember how to decided this problem but it was be releated with initialisation order for widgets before other operations (Especcially with progressbar operations and threads) and there were the problems exacly with combo widget. Why? I don't know. Try check an initialisation data for Combo. Maybe you create Combo in one place but set data for them in other
