Description of issue:
When for some parameter set a value which is out of rage or inaccurate and than click to another parameter,
receive a warning message dialog with description of a problem.
After closing of this Dialog any button on settings tab doesn't work for first click.
Looks like after dialog is closed Notebook page loses a focus.
Workaround:
Use self-created WarningDialog (inherited from the wxDialog) instead of wxMessageDialog
