=========================================
Tried to reduce the width of a column in a grid control in a form by shifting the right border (with the mouse) a bit to the left
Comment 1 Alex Thurgood 2018-12-10 09:38:49 UTC
@Gisbert : please provide a sample database file with which we can test.
Comment 2 Alex Thurgood 2018-12-10 09:45:50 UTC
On macOS 10.14, I get a permanent beachball hang of the application when moving the right cell border to the left (reducing width) in a grid control on a hsqldb query-based form.

Attaching test DB for testing.

1) Open the form qry_DATE in form design mode (right mouse button click > Edit)
2) Try moving the right border of column COMPANY1 to the left.
3) Hang requiring forced kill.

I have to interrupt the lldb session with Ctrl-C in order to get a back trace, which I have enclosed, FWIW.

either.

@Alex Thurgood, Could you please try with a clean profile ? I'm wondering if you hang was related to bug 121778

My master build from 12/12 always uses a fresh profile.

Still reproducible.
Open ODB file
Open qry_DATE in Edit mode
With mouse, select and slide right border of 2nd column to left and release.
With mouse, select and slide right border of last column to left and release.
With mouse, select and slide right border of 3rd column to left and release.

Forcibly breaking LO process (Ctrl-Z) to regain control in lldb gives :
