Hi all,
A strange thing happens in the subgrids of a form (about 10 subgrids).
When one or more records are selected, the subgrid columns all shrink together.
Before selection:

After selection:

Only a refresh of the page brings the columns back to their initial size.
There is no custom javascript that interacts with the subgrids, no subgrid has been modified in any way.
Standard configurations only: creation of column views and placement in the form.
The problem occurs on all 10 subgrids of the form.
Anyone know what this problem could be and how to fix?
Thank you in advance!
