CrystalReportsViewer v.14 in Export Dialog 'From: ' 'To:' fields enabled but cannot insert value in IE 8

Hi,

I'm working on issue in Crystal Reports, i believe it is issue in CrystalReportsViewer:

In IE8 for some reason in Export dialog, for export to pdf I cannot modify From:  and To: pages on the dialog. In IE9, IE7 dialog seems to be working fine.

I noticed that logic in html behind 'From text field' looks in html:

<input oncontextmenu="event.cancelBubble=true;return true"

    style="width: 50px; margin-top: 1px; margin-bottom: 1px; padding-left: 5px; padding-right: 2px; height: 16px; margin-left: 0px;"

    onfocus="_CW.TextFieldWidget_focus(this)" onblur="_CW.TextFieldWidget_blur(this)"

    onchange="_CW.TextFieldWidget_changeCB(event,this)"

onkeydown=" return _CW.TextFieldWidget_keyDownCB(event,this);"

onkeyup=" return _CW.TextFieldWidget_keyUpCB(event,this);"

onkeypress=" return _CW.TextFieldWidget_keyPressCB(event,this);" type="text"

ondragstart="event.cancelBubble=true;return true"

onselectstart="event.cancelBubble=true;return true"

class="textinputs textDisabled" id="<id>" name="<name>" title="" value="" disabled=""/>

I suppose that input element events don't work properly for some reason..

The question - where can I find javascript source functions behind these events to change them?

May be try some other idea?

Thanks!
