Impress projector & alphabetically numbered lines

Libreoffice is a great office suite. But I have to raise these 2 questions to you, hope
you may improve it :

  • Impress show slides nicely on the SCREEN of my computer, with very useful tool ‘mouse as a pen’;
    but when the computer is connected to a projector, Impress changes to a very different and
    unpleasant mode automatically : one slide is showing and a upcoming thumb one waiting there;
    that’s okay, since this is one mode of ‘show slides’. But I don’t think this is the mode anyone
    would like, because there is only one way to change the slide: clicking on the arrowheads on the
    screen because mouse wheel is inactivated. Also, the projected slide is much smaller in size,
    since the arrowheads occupy a part of the screen area. Mouse tools are inactivated also, so one
    has no way to freehand-write anything, or uses it as a pointer.

I guess the situation can be changed by ‘property’,or ‘preference’, but failed to do so.
Or, Impress is not equiped with proper drivers and cannot recognize the projectors ?

  • The 2nd unpleasant thing in Impress I found is that in some unpredicted cases Impress formulates
    the slides being composed automatically. At the begining of each line, a capital letter is given
    unconditionally so that the lines are alphabetically numbered. I cannot find any way to delete
    these unwanted and un-necessary letters; I don’t think anyone would like such an out-of-control
    way of composing. I have a screengrab picture, but don’t know how to attach here.

The Linux distro I use is Porteus, so Libreoffice is in module form.
I tried these modules:

06-libreoffice.xzm > from www.porteus.org repository, newer one;
libreoffice_4.0.4.xzm > contributor made.
