If these lines are green horizontal or blue vertical then:
It's not a bug, it's a feature. They are called guidelines. (Delphi lacks them). They help you to align components to another. You can switch them off in the environment opts.

Huh, there are still some very nasty 'bugs' in the designer (e.g. capturing, keys, parent-child relationships, form names). They are simply not implemented, but there are no warnings, so you won't notice that sometimes things goes wrong. So I call them bugs.

Yep, I noticed this tomorrow. There were also a lot of mem leaks, which I fixed one minute ago.
It came together with some stuff on monday. Hopefully this can be fixed soon...

Don't know yet. I had not yet the time to track it down. But probably designer.pp, controls.pp, gtkobject.inc or gtkcallback.inc.
