Acrobat check boxes filling inconsistently
Hi all,
I have just created a form for a client and despite having created all check boxes in exactly the same way some are filling with bigger boxes than others, when I preview from Acrobat everything looks consistent as you can see in the first screenshot, when I open in Acrobat after saving, again everything looks great. However if I open it using any other programme like Preview or view it through Finder then the fill on those check boxes is inconsistent.
Any advice would be appreciated! I didn't notice until the client queried from his end so the software he is using is obviously showing the fault.
