Acrobat Form Checkboxes/Radio Buttons
I'm having an issue with newly created checkboxes and radio buttons.
They're set to have a cross in them when clicked, but in use nothing appears when they are clicked.
This is a problem which has been creeping in over a period of time when creating checkboxes or radio buttons and I was previously able to fix it by setting the default style to a checkbox, within the document i'm updating, I know is working correctly, but even this doesn't work now.
I've tried different fills (check, circle etc) but the problem persists. I've tried new/blank documents, but again no luck.
Has anyone else encounted this or knows of a fix i could try?
Thanks
