QT designer 3.3.5 and 3.3.8b is mismatching in QCheckBox allignment

[soumyadeep_pan]

I have developed an application (static method) in FC9 (Default qt version installed 3.3.8b), which I am running FC5 (Default QT version installed 3.3.5). But the alignment for square box in QCheckBox are different in two different version, for QT3.3.8b it is in the middle, for QT3.3.5 it is left aligned . I have uploaded screen shots for reference.
Is there any way to set the square box in QT3.3.5 to left alignment (statically) ? The whole application is developed and it must execute on FC5 system, so is it possible to install QT3.3.8b in FC5 ?
How I can solve this problem ???? Thanks in advance.
