Test was failing if JComboBox tests was run in group in nightly mach5 testing. Modified test to move frame to centre of screen, add delays before frame show. Also updated the test that ran just before this test move frame to center of screen. Resultant modified test ran fine in JComboBox group and also in standalone, several iterations of which are ran in mach5. Link in JBS.
