Not able to select image while using float property

When i using float property in image ... i am not able to select the image. If i am not using the float property i am able to select image. In red color line is my problem when i using the float property of image.

My code:

public function selectionChangeListener(event:SelectionEvent):void

{

          var cTF:TextFlow = event.selectionState.textFlow;

            // slect the correspondent managers for this selection

            if( selectManagersByTextFlow( cTF ) == false )

                return;

selectionState = event.selectionState;

            selectedElementRange = ElementRange.createElementRange(selectionState.textFlow, selectionState.absoluteStart, selectionState.absoluteEnd);

            characterFormat = textFlow.interactionManager.activePosition == textFlow.interactionManager.anchorPosition ? textFlow.interactionManager.getCommonCharacterFormat() : selectedElementRange.characterFormat;

            paragraphFormat = selectedElementRange.paragraphFormat;

            containerFormat = selectedElementRange.containerFormat;

            var linkString:String = "";

            var linkTarget:String = "";

            var linkEl:LinkElement = selectedElementRange.firstLeaf.getParentByType(LinkElement) as LinkElement;

            if (linkEl != null){

                var linkElStart:int = linkEl.getAbsoluteStart();

                var linkElEnd:int = linkElStart + linkEl.textLength;

                if (linkElEnd < linkElStart){

                    var temp:int = linkElStart;

                    linkElStart = linkElEnd;

                    linkElEnd = temp;

                }

                var beginRange:int = selectedElementRange.absoluteStart;

                var endRange:int = selectedElementRange.absoluteEnd;

                var beginPara:ParagraphElement = selectedElementRange.firstParagraph;

                if (endRange == (beginPara.getAbsoluteStart() + beginPara.textLength)){

                    endRange--;

                }

                if ((beginRange == endRange) || (endRange <= linkElEnd)){

                    linkString = LinkElement(linkEl).href;

                    linkTarget = LinkElement(linkEl).target;

                }

            }

           if(selectedElementRange.firstLeaf is InlineGraphicElement){

                var inlineGraphElement:InlineGraphicElement = selectedElementRange.firstLeaf as InlineGraphicElement;

                showHideImageHandles(selectedElementRange.absoluteStart);

            }

            else{

                dispatch(new ImageHandlesEvent(ImageHandlesEvent.HIDE, -1, 0));

            }

}

Thanx in advanced.
