Hi,
Thank you for posting in the Microsoft Community Forum.
From your description I understand that you are receiving error message ESET and Event ID: 623 while using Internet Explorer 9.
To understand the issue better, please answer the following questions:
1. Is the computer connected to domain?
2. When exactly you receive this error message?
3. What do you mean by ‘Internet Explorer 9 Restore Closed tabs stopped working’?
4. Is the issue persisting while browsing any website or opening new tab?
Get back with more information to assist you better.
1. I'm not sure exactly what a domain is. My single desktop is connected to nothing but an ISP cable and an old printer. The first connection is designated a Home Network, but there is no HomeGroup. I have three User Accounts--two with Administrator status and one Standard.
2. Received only once (see my question). Date: 10/16/2012 6:46:58 PM
3. Only my Standard User Account has this problem:
In IE9 (32 or 64), if I open two tabs and then close one of them, I cannot reopen it either by right-clicking the home tab and choosing Reopen Closed Tab or by opening a blank tab and choosing the same command on the lower left. Nothing happens. The problem applies to multiple tabs also, but it is absent when I use either of the other two User Accounts.
4. Only the one error message. I don't know what I was doing when it came in. It hasn't appeared again, but the message says I need to "commit or roll back a long-running transaction." I have no idea what transaction or where because I don't understand the terminology of the message.
What is ClientDataStore? Please explain what they are talking about; it sounds like a problem that is growing.
11/22/2012 UPDATE
I cleaned up my User accounts' permissions, and my Reopen Closed Tabs and another minor browser problem are gone--aparently unrelated.
I still wish someone would explain the above ESENT error to me. Just what is about to stop being updated?!
