I am not aware of any current technical issues on our side of things that would explain why Internet Explorer has been randomly closing on your when working within your Auctiva account, so I feel it would be a good idea to your browser cache and then restarting your Internet Explorer browser and see if your experience improves thereafter.
In order to clear your cache in your Internet Explorer web browser, please select "Internet Options" from the "Tools" menu (has an icon that looks like a gear and it in the upper right corner) within Internet Explorer. Then, under the "General" tab, click the "Delete" button in the "Browsing History" section.
On the ensuing pop up window, make sure "Temporary Internet Files" and "Cookies" are selected and click the "Delete" button below.
Once this process has been completed, close and re-open your Internet Explorer web browser for the changes to take effect. Also, please ensure that only one browser window is open when you are doing this or your cache may not empty properly.
If you continue to encounter similar difficulties after clearing your cache, please contact our Customer Support team directly from under the “Help” tab within your account and we will be happy to continue working with you on this.
As Foofighterubu, using another browser we support (such as Mozilla Firefox or Google Chrome) is also an option. If you do not currently have either of these alternate browsers installed, they can be downloaded at no cost using the respective buttons in the “Latest Browser” section of our FAG page located at: https://www.auctiva.com/help/faq/most-commonly-asked/
