I have changed the index_edit.php file to provide a link in the popup window for closing the popup box and refreshing the screen, so the changes that are made are visible immediately.
In line 231 of the index_edit.php file you find this line:
print $pgv_lang["config_update_ok"]."<br />\n";
I changed it into this line:
print "<center>".$pgv_lang["config_update_ok"]."<br /></center>\n";
print "<center><br /><a href=\"javascript:;\" onclick=\"if (window.opener.refreshpage)
window.opener.refreshpage(); window.close();\">".$pgv_lang["close_window"]."</a><br /></center>";
When you now edit a block and you click on the link, the popup box will close and the window will be refreshed.
It would be nice if something like this could be in the next version of PGV
PGV used to operate in this fashion - when the new configuration was saved, the WELCOME or PORTAL page would refresh, displaying the blocks in their new configuration.
