I can't resize the columns of a DBGrid at run time using the mouse.

I get the resize cursor when hovering over the header junction between
columns but no resize.

This is latest Lazarus on a Mac.

Hi pat03uk,

I was able to reproduce this behavior. If you have a silent exception
on the OnMouseDown event linked to the DBGrid, you will not be able to
resize columns.
Check if you have any overloaded events related to the mouse action on
your DBGrid that are not raising exception.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  Procedure
TfmMainDemo.grdProjectMouseDown(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);Begin   // Simulate a silent
exception   Abort;End;

Thanks for that. I will check but I have since tried KDBGrid, RXDBGrid
which work as expected. Then I went back to DBGrid and that now worked
fine as well. So I don't know what the problem was.
