[lazarus] Bugs in Editor and with scrollbars

[Jens Arm]

Hi

	The new editor is much better and quicker than the old editor,
	but the cursor is sometimes shown and sometimes not. After the start
	of Lazarus it is shown in the editor, but if I open a second editor
	the cursor is hidden, but the writing is working (however you don't
	know where you are writing). It is also hidden when you change the
	console.
	If I try to scroll down or up in the editor with the scrollbars
	the source will be marked. The scrollbars is the property editor are
	also not working correctly.
	The moving of controls in the form editor is not working
	correctly. If you move a component it jumps to the left top corner and
	then again where the mouse pointer is and so on.
	If you change the size of the editor with the left and right
	border, so that the editor is so small as it can be, you get a
	SegFault:
