Hi Gill,
Sorry about the delayed response but I'm actually unaware of the problems you are describing. You may want to try the following measures, which may improve the performance of Auctiva on your computer:
1) Clear your browser cache.
2) Make sure you have installed all current Windows updates. These are available at http://www.microsoft.com
3) Make sure you are running the latest version of your browser, either Internet Explorer 6.0 or Mozilla Firefox 1.5. If you’re already using one, you may want to try the other. A free download of Firefox is available at http://www.mozilla.com
4) It also may be worthwhile to run a spyware and adware removal program. There are many product downloads available for free or cheap at http://www.downloads.com. AdAware and Spyware Doctor are among the most popular of these programs.
5) Also, you should run an anti-virus program on your computer if one is available to you.
I hope some of this info helps=) I wish I had suggestions more specific to your situation to give you but...I don't.
