Today I mentioned that if you define a byte array with a length of 100 the debugger doesn't show the array's content when you move the mouse over it. Not a big thing but took me some time to realise ;-)
This doesn't work (mousepointer over "PWBytes" shows an empty window)
B4X:
Dim PWBytes(100) As Byte
PWBytes(0)=55
Any other value will work (99, 101, 200). Only 100 not.
