Below are the radiogroups at design time:

At run time, the lower of the two looses part of the right hand side:

The captions have CaptionSkin as COLHEADER and the anchors are [akTop,akRight]. The CaptionLayout of both is clTopRight.
Strange thing is, only the bottom radiogroup is in trouble!
The radiogroups are place on a TsTabSheet, which is part of a TsPageControl, which is placed on a TsPanel, which is placed on another TsTabSheet, placed on a TsPageControl, placed on a Frame with a TsFrameAdapter. The frame is placed on a TsTabSheet of a TsPageControl on the main form.
You can imagine it is a bit of a hassle to reproduce this in a test project.
