Hi Raymond,
Sorry for the inconvenience caused.I have tested this issue by creating a sample using GridBagLayout in v.4.1.0.50 and then again tested by upgrading to 4.1.0.62. I was not able to reproduce the issue.
I have attached the tested sample:
GridBagLayout.zip
Could you please let me know the controls you are using in the gridBagLayout form? Also, let me know whether you are localizing the gridBagLayout constraints in your form.
Thanks for your patience.
Best Regards,
Seetha
