Hallo,

this is my first 3d on this forum.

When I play my PHP/JS project in Firefox some errors happen and the grids often do not load.

The errors – shown by Firebug – are each time different in number and type.

For example…

… on first start…

$.jgrid.extend is not a function
restoreRow : function(rowid, afterrestorefunc) {

… after pressing F5…

no error happens

… after a further F5…
