CheckBoxColumn strange behaviour

Hi,

I was using 1.4.53 and noticed a ctrange behaviour with a CheckBoxColumn in a DGV. Checking and unchecking works alright most of the times. However, after some checks/unchecks, it stops working for a row. When I try to check the checkbox in that row, it simply does not check but the focus moves to the previous row. The CellValueChanged event does not fire for that row. If I check a checkbox outside the DGV, that checks all rows programmatically, things start working again. Till it gets stuck again.

I tried with 1.4.59 but the behaviour is the same. I saw other threads about checkboxcolumn, but here the problem is different, the checkboxcolumn in general works alright, it does not work only for a single row.

And I don’t know how to reproduce…

Best,
Alex
