BUG? Lots of columns - clicking registers wrong column

I’m using the unit view, and on some instances there may be a very large number of columns (say 30). When I click or drag on a column towards the right, it is responding in the wrong column. That is, the cursor seems to think the columns are a slightly different width than they actually are. So over to the left, it is correct, but gradually towards the right of the screen the offset means that by the right, you are a whole column out.

I presume this is a bug in the software, but can you please advise if there is aworkaround?


In the sample all work properly. Could you share with a demo link, where the problem can be reproduced?
