I am aware that this question has been asked once, however the solution for them didn't work with me.

Whenever I go to open/save a file in any program, the dialog does not come up, and the application goes to 'Not Responding'. This goes on for about a few minutes, and then stops, but still does not open the dialog.

There have been a few occasions where the dialog has suddenly worked for a while, but then the problem comes back.

I have tried many solutions given around the internet, I have cleaned it with CCleaner, disk defragged it, sorted the index. Nothing works. Is there anybody who has any idea what the problem is?

This is Windows Vista. I'm not quite sure what kind of information you guys would need about my laptop, but I'll give you it if you need it. :)

Solutions I have Tried: I have tried deleting the 'Shellicon' folder in the registry, which wasn't even in there. I have looked for mapped network drives lingering around, and I haven't come across any. I have tried rebuilding teh Widnows Search Indexes...no difference.
