I think I know why. I actually wrote about the issue here: https://www.b4x.-a-bit-embarrassing-is-this-a-bug-or-am-i-going-stark-raving-mad.98882/post-622810. 0xFFFFFFFF and even 0x80000000 are actually string literals of numbers. Both fit in the size of an int, so they are casted to an int and then

The beauty of 2's complement is that if you start at the minimum and keep on adding 1, you'll eventually get to 0xFFFFFFFF = -1 Now if you add 1 you get 0x0100000000 which in a 32 bit window is 0x00000000 = 0 Then you keep on adding 1 until you get to 0x7FFFFFFF which is the maximum. If you add 1 mo

There are numerous threads in the forum about this, but I didn't have much luck with them. I wanted to disable the suggestions, but they always showed. I saw one suggestion setting the field to be for email, which disabled the suggestions - but that's clearly just a dirty workaround. This is the re
