The instruction to group objects (in this case images, or images + text box) simply doesn’t work.
Updated my LO version to 18.104.22.168 (x64) but no diffrence.
Holding down Shift key (nor any other ) according to instructions does not work : unable to select more than one object.
LO version to 22.214.171.124 (x64)
