Cursor will not die!

I have a problem where a stored procedure will only work once per session. If I create a new query mgr window it will work again - but only once. Same deal when called from an ASP page - will work once per session.

The procedure has a cursor & a @@FETCH_STATUS while loop. At the end of the loop the cursor is closed and deallocated.

I did a test to return the FETCH_STATUS variable and it comes back -1 and the loop does not run - so no recordset gets created unless it's the first time the procedure is run.

Any clues on why this is happening? and how to really kill the cursor at the end of the procedure run thru?

Many Thanks !

Thanks for replying. It's the strangest thing (well to me anyway) - the code works exactly as I want - problem is it will only run once. Any further calls from the same session = an empty recordset. It's because the cursor remains at the end, even though it's been closed and deallocated.
Code:
CREATE PROCEDURE dbo.getphotosbypage
@UserID int,

AS
DECLARE @pagecounter int,
@monthcounter int,
@priorDate datetime,
@photoID int,
@comments varchar(500),
@nextdate datetime,

CREATE TABLE photos_temp 
(monthcount int, 
photoID int, 
comments varchar(500), 
dateuploaded datetime)

set @monthcounter = 1

DECLARE photos_cursor CURSOR FOR
SELECT photoID,comments,dateuploaded FROM Photos
WHERE UserID = @UserID
ORDER BY Dateuploaded

OPEN photos_cursor

WHILE @@FETCH_STATUS = 0
BEGIN

FETCH NEXT FROM photos_cursor
INTO @PhotoID, @comments, @Nextdate

if datepart(mm,@nextdate) <> datepart(mm,@priordate) OR
datepart(yy,@nextdate) <> datepart(yy, @priordate)
BEGIN
SET @monthcounter = @monthcounter + 1
END
If @priorID <> @photoID 
BEGIN
insert into photos_temp (monthcount,photoID,comments,dateuploaded)
values (@monthcounter, @photoID, @comments, @Nextdate)
END
SET @priordate = @Nextdate
SET @priorID = @photoID
END 

select * from photos_temp

SET @photoID = null
SET @comments = null
SET @nextdate = null
DROP TABLE photos_temp
CLOSE photos_cursor
DEALLOCATE photos_cursor 

GO
