Mouse problem

Hi,
trying to develop a different navigation for vizard, Iím having three problems with the mouse commands:

1. When I bring the mouse up, at a certain position close to the top the program throws it down (MOUSEMOVE_EVENT), the same happens at the bottom, the mouse gets pushed up at a certain positon.
2. Also, when I click the Ďtabbí and the left mouse-button (in the program below) and release the mouse and tabb again, the view still changes and moves in, also I did not program that.
3. How could I implement a keyboard-command that getís only triggered if the user presses shift+ctrl (this question is not very important, so if it is complicated I just take another key).

Steve




Code:
view = viz.get(viz.MAIN_VIEWPOINT)
view.translate(2.50, 1.01, -0.25)#1.3269580602645874, 1.013837456703186, -0.55598777532577515)
view.rotate(-90,0,0)


mouseIsMovingUp=1
pointIsMovingRight=1
pointIsMovingUp=1

oldMousePos=0
currentMousePosX =0


def mykeyboard(whichKey):
	print 'This key was pressed: ', whichKey
	if whichKey == viz.KEY_CONTROL_L:
		viz.mouse(viz.ON)
	if whichKey == '65289':
		print'tabb',pointIsMovingUp
		if viz.buttonstate()==1:
			if pointIsMovingUp==1:
				viz.mouse(viz.OFF)
				print 'pointIsMovingUP==1'
				#print 'viz.get(viz.MAIN_VIEWPOINT):', view.get(viz.HEAD_POS)
				view.translate(view.get(viz.HEAD_POS)[0],view.get(viz.HEAD_POS)[1]+.05,view.get(viz.HEAD_POS)[2])
				return
			if pointIsMovingUp==0:
				viz.mouse(viz.OFF)
				print 'pointIsMovingUP==1'
				#print 'viz.get(viz.MAIN_VIEWPOINT):', view.get(viz.HEAD_POS)
				view.translate(view.get(viz.HEAD_POS)[0],view.get(viz.HEAD_POS)[1]-.05,view.get(viz.HEAD_POS)[2])
				return

viz.callback(viz.KEYBOARD_EVENT, mykeyboard)


def mymousemove(horz, vert):
	global mouseIsMovingUp,pointIsMovingRight,pointIsMovingUp, oldMousePos,currentMousePosX
	
	if vert>0:
		mouseIsMovingUp=1
		pointIsMovingUp=1
		print 'up'
		return
	if vert<0:
		mouseIsMovingUp=0
		pointIsMovingUp=0
		print 'down',pointIsMovingUp
		return


	#print 'horz, pos',horz, pos
	if horz>currentMousePosX:
		pointIsMovingRight=1
		#print 'in right1'
	if horz<currentMousePosX:
		pointIsMovingRight=0
		#print 'in right0'
	
	oldMousePos=currentMousePosX
	currentMousePosX = viz.mousepos()[0]
	print 'oldMousePos',oldMousePos,currentMousePosX


	#print 'My mouse moved to: ', horz, vert
viz.callback(viz.MOUSEMOVE_EVENT, mymousemove)



#def mymouse(whichButton):
#	if whichButton == viz.MOUSEBUTTON_LEFT:
#		#viz.mouse(viz.ON)

#viz.callback(viz.MOUSEUP_EVENT, mymouse)
