I am using a Surface Pro Tablet and noticed that when I enter a Pop-Up Menu field, the font size is very small. However, after I choose the value and release, the font size is normal. I assume this is a Tablet issue, because when I use the same Database on my Lap Top, the font size appears to be normal when choosing it.
I have exactly the same problem with Microsoft Surface Pro 4 and Filemaker 14.04. I posted a question about this in this forum (called : Very small typeface in popup) but I didn't get any reply, not even from Filemaker. I tried everything, but I cannot resolve the problem. Do you have a solution in the meantime?
