the simple macro below that used to work in LibO 4.2.5 and earlier releases doesn't work anymore in LibO 4.3.0.1 and 4.3.0.2 under Win7x64 and WinXP, unless it is modified as it follows.

---------------------------------
original 4.2.x macro code
---------------------------------

Sub RemoveTextHighlighting

dim document   as object
dim dispatcher as object

document   = ThisComponent.CurrentController.Frame
dispatcher = createUnoService("com.sun.star.frame.DispatchHelper")

dispatcher.executeDispatch(document, ".uno:BackColor", "", 0, Array())

End Sub


---------------------------------
modified 4.3.x macro code
---------------------------------

Sub RemoveTextHighlighting

	Dim document   as object
	Dim dispatcher as object

	document   = ThisComponent.CurrentController.Frame
	dispatcher = createUnoService("com.sun.star.frame.DispatchHelper")

	REM We need to define the args for the dispatcher. without this the backcolor will not change.
	Dim args1(0) as new com.sun.star.beans.PropertyValue
	args1(0).name = "BackColor"
	args1(0).value = -1

	dispatcher.executeDispatch(document, ".uno:BackColor", "", 0,args1())
	
End Sub

---------------------------------

to test the macro just highlight some text on a Writer document then select it and run the macro. it should remove the highlight.

I set status as NEW because of independent confirmation here:

has the BASIC interpreter changed in 4.3.x ? 
why the same code that works in 4.2.x doesn't works in 4.3.x ?
