Invisible objects / changing text

Chaps,

I have a couple of controls on my form that are behaving badly during runtime.

Firstly, there is a CheckBox next to the text "Simplified:" that on start up only appears once my mouse has passed over. To my knowledge I haven't set such an action, just the default settings for a new control. See image 3 and 2.

Also, The text element "Type paal:" gets bolder if the option lists Stijf and Links are clicked. See image 3 and 1.

Any idea why or how to fix this?

This kind of behavior sometimes indicates an endless loop of some kind, with an endless cycle of events causing each other to fire. I'd start by removing events until the problem goes away, or all events are removed. If the problem persists with no events at all, I would start removing controls, and finally replacing misbehaving controls with new ones. You'll likely find the culprit eventually, and then it will be easier to determine the actual cause.
