Query regarding jumping components in a Kylix form.

I'm working with the Borlund Delphi 7 environment, attempting to make an addition to a program built using Kylix by my predecessor in this position.

I've made a few additions to this in the past, but I'm getting stumped by something that's happening now. It won't cause a problem for the end user as far as I can tell, but it makes it seriously annoying to build the form.

The form I'm working on is designed to be a Poll-style survey - just a series of Yes/No questions. I'm setting these up as RadioGroup components spread across a pair of groupboxes. Each groupbox represents one larger area, and the Radiogroup items in each one are related to one another.

There are enough items I have to have the form maximized to view everything. I mention this because I believe it may be related to my problem.

When I've got the screen maximized, I can move the individual Radiogroup components around freely. When I've got the form reduced in size (so as to manipulate the names/captions of the Radiogroups), I can't. Moving a Radiogroup in the lower of the two Groupbox components, even by accident, causes them to fall to the lowest possible point on the on the groupbox, although their X-axis position doesn't change. I cannot raise them any higher than this afterwards.

Again, it's not really critical, as I don't forsee this causing any problems for the end users, but having a component vanish when I click on it because I accidentally jittered the mouse is somewhat frustrating.

Anyone have any suggestions as to what my problem might be?
