Thanks for the pointers. Seems it something used by the System Browser, as it occurring whenever I try to do something with it.

It looks like you have a nil object that's getting sent the message #categories.
If you dive in with the debugger, somewhere near the top, you should be able to find your nil object. Nil has a way of begetting nil sometimes, so you may need to walk down the stack tract to find original the source of the error.
If all else fails, you should be able to recover most if not all of your code from your .changes file.

Hi
I've been using a Squeak 4.1 and Seaside 3.0 and I think I must have stuffed something up as now getting the following error:

I would just use a new copy of the image but I need to fileout some package I've written but this error is stopping me from doing so. Any ideas ?
Thanks
