I've just come back from Norfolk and noticed a lot of vignetting on some of my shots, mainly the ones where I used my wide angle at its widest with a polarising filter on the front.
Any suggestions for editing it out using PSP? Other than cloning?
Can't help you with PSP, but just so you know what's going on:
Your polarizing filter is probably fairly thick (i.e. it sticks out from your lens further than most filters). The reason is simple... you have to have room for the filter mount, the filter, and the rotating ring. So they tend to be thick. But on a wide angle lens, the further away from the front of the lens you get, the more likely you are to be within view of the lens.
So, a couple of solutions:
1) Buy a very thin polarizer (these tend to be pretty expensive), or
2) Buy the cokin system filters. With these, you can actually buy a set of filters that are larger than your lens and that will let you cover more of the viewing angle of the lens.
I recommend the cokin system anyway for when you want to use Graduated Neutral Density filters.
Add more vignetting and make it look like you did it on purpose.
For wide angle lens, there's a polarizing filter that not as tall. I forgot what it's called, but it's a little more expensive. I bought one for my 24mm. I doesn't have the threads on the end of the filter, so it won't vignette as much. (I actually don't know since I've only used it on my 10D with a 1.6 crop.)

I can second the recommendation for the Cokin series - the P series is the one you would probably want to go with, but cannot be used with super wides such as the Canon 10-22. For a super-wide you would need the z series, which becomes appreciably more expensive.
One question I have for you Soulman, did you also have a UV filter on the lens at the time? with my 18-70mm nikkor lens I have to remove the UV filter to put the polerizer on or my pics suffer the same fate as yours. Hope this is helpful.
If you don't want to use a Cokin set, you can buy a polarizing filter a little larger than your current one, and purchase a step-up ring. The thinner the better.

dwterry is right. Standard thick polarizers with front threads will cause vignetting at wide angles. They make wide-angle polarizer to eliminate the problem. They are expensive. I looked a B&W brand one that was $240.
