When you open parallels there's a check for updates option in one of the menus (either parallels or help I think).
Try that first, then it might be worth changing the connection settings for parallels. Think I had to do that to get it to work - will check later.
By Jove, I think you were right, it looks like reinstalling parallels tools has done the job. It's early doors yet, but my cursor isn't jerking anymore. You're now officially my favourtie person that has anything to do with Bongos, including the makers of Um Bongo!
Grrrrrrrrrrrrrrrr and there I was about to send you to my items for sale on ebay, and yes I do sell 2nd user laptops and not all of them have naff batteries, all batteries are tested and the time they last our documented in the ebay description.
To be perfectly honest the feedback system is a great guide on ebay, obviously like anything it is not 100% safe but someone with a large number of feedback and anything from 99.5% is a good guide as to whether the items are going to be as described.
A lot of people diss ebay but the fact is it is now the biggest retailer in the UK in terms of turnover and internet sales are the future for the UK especially once the recession hits home in the next 12 months or so.
