MForms radio buttons (and check boxes) rendering random widths (no replies)

Hello,

I am facing a problem with a UI that randomly changes the component width on subsequent dialog displays.

Sequence of images here:

Wrong ones:

Top image is as it should render. Notice the random left aligns with all other images.

What's wrong here?

Here's the code that creates the UI:

from mforms import *
from abc import ABCMeta

@ModuleInfo.plugin(...)
@ModuleInfo.export(grt.INT, grt.classes.db_Catalog)
def export_jpa_annotated_classes(catalog):

    do_export = Builder.ask_for_options()


class Builder:

    __metaclass__ = ABCMeta

    supported_java_versions = ['5', '6', '7', '8', '9', '10', '11']
    supported_jpa_versions = ['1.0', '2.0', '2.1', '2.2']

    @staticmethod
    def ask_for_options():
        """Ask the user for the options on the current MWB model file and returns True if the user pressed OK and False if the user pressed cancel."""

        java_version_lb.set_wrap_text(False)

        java_version_bx.add(java_version_lb, False, True)

Maybe it's something for the WB team to look at, as it is absolutely not understandable why this is happening...

I'd very much appreciate if you could have a look at this.

Thanks and happy new year.
