A le voile.... I need to refresh a grid coming back from a sc_redir.

Hi ,
I got a sarting_grid and I’m using on click event to redir to another application with the usual global value of row ID. The application print a label and then I have a last row that makes a sc_redir(starting_grid). I used also sc_redir(starting_grid,_blank) but nothing changes.
When I come back the problem is that the grid seems blocked to a strange status.
If I refresh the url it starts correctly again .

I’m wondering why this happens and wich is the best method to return to starting_grid refreshing it .

code used
$file_print_sato= “…/z_config_files/print_sato.php”; // This print a label on thermal printer
sc_redir($file_print_sato);

sc_redir(…/bridge/grid_dbo_Wristband.php); // This is the starting_grid with a Friendly URL ‘bridge’
