Hi everyone I'm fairly new to PTE although learning fast, so please excuse my question if it has already been asked before. I've searched the forum but can't find any reference to it. I would like to know if a background colour can be added to text boxes so that captions can easily be read in situations where the colour of the text tends to blend with those on a similarly coloured picture. I realise that a coloured rectangle of the same size could be placed behind a text box but this would be very fiddly to do for every slide - or can the two be locked together? Thanks in advance
