Description of the Bug:When a dialog is about to be displayed, Windows computes the width of each tab to determine if they should appear on a single row or multiple rows. GenoPro was supplying the text "Custom Tag" for computing the tab layout. As a result, a long text was not considered in the layout, and therefore the layout was often on a single row instead of two rows. This fix is not perfect because GenoPro uses Unicode and the dialog captions are non-Unicode because of the MFC framework. This fix should work 99.9% of the case. In the case of the 0.1% not working, just change the name of your dialog layout to something shorter or longer.
Eventually GenoPro will rewrite its own library to remove any references to MFC stuff.
