When I'm viewing an album on my Iphone (and a mobile browser on a Kindle fire), a left arrow appears on the lower left of the screen and covers the first couple letters of the caption.  If I click on the left arrow, a right arrow image shows up about 1/2 inch to the right. Clicking on them does nothing.

I'm wanting to get rid of these arrows but can't find out how to do it.  I've put a "ShowNavButtons="false" in the config file hoping that would get rid of them but then the gallery won't load (the spinner just spins).

Here are my settings:

maxImageWidth="1024"
    maxImageHeight="768"
    imageQuality="80"
    thumbWidth="85"
    thumbHeight="85"
    thumbQuality="90"
    useFlickr="false"
    resizeOnImport="true"
    cropToFit="false"
    showThumbsButton="true"
    useFullscreenExpand="true"
    galleryTitlePosition="OVERLAY"
    galleryTitleHAlign="LEFT"
    imageClickMode="NONE"
    captionPosition="OVERLAY_IMAGE"
    showImageNumber="false"
    indexPageName="listing.html"
    enableDirectLinks="false"
    enableLooping="false"
    showNavButtons="false"
    showOpenButton="false"
    showExpandButton="true"
    showSmallThumbs="false"
    showLargeThumbs="true"
    useThumbDots="false"
    showThumbPagingText="false"
    thumbNavPosition="CENTER"
    imageScaleMode="SCALE"
    maxCaptionHeight="100"
    galleryTitle="Photos"
    textColor="rgba(255,255,255,1)"
    showImageNav="true"
    imageNavPosition="IMAGE"
    imageFrameColor="rgba(255,255,255,1)"
    thumbFrameColor="rgba(255,0,102,.5)"
    thumbSelectedFrameWidth="3"
    backButtonUseIcon="false"
    backButtonPosition="NONE"
    captionHAlign="CENTER"
    captionBackColor="rgba(0,0,0,.7)"

Any ideas?
