Gridag-Layout problem in motif look and feel.

[nretharekar]

I have created GUI window using gridbaglayout. Window contains 1 columns and 2 rows. First and second row contains two JButton with no vertical space. If i set java and window look and feel it work perfectly fine but when i set motif look and feel vertical space automatically appears. Not able to understand. If somebody is having solution please let me know as early as possible.
