ok - so I look more closely. waht seesm to happed is that sometimes the (mouse) cursor does not move after typing into the field & pressing enter or arrow. if moves maybe at the 2nd or 3rd press. I just done several trying to recreate an exact error sequence but it is hit n miss.
it is most noticable if there is an existing letter in the box, say , Y
I double click the box, which highights the Y, I type Z, which overwrites it. I press enter & nothing seems to happen. the box appears to be stil open for editI press enter some more & it sorts itself out.
what is also fogging the isseu is that as I type the Z, a 2nd box displays under the one I'm typing in, with a Z in it, as if the program is suggesting an input value to me?
most confusing when working down a vertical column, amending fields as I go.
it's a very minor issue but I think something is not 100% right here.
