Interactive form (made in Indesign, not Acrobat, as I don't wanted to mix!) - I wanted an option box (checkbox) to have a cross instead of a circle. The only option was to take a "sample button" from the menu. I choose the option box with a cross (R10) and integrated it in the form. After exporting to Acrobat, firstly there was a cross when I clicked on the box. But when I was going onto another step (next box, print file, etc.) the cross was changed in a circle again. There was no possibility to keep the cross in the place!!!!
