I install and uninstall a lot of software on my laptop in the course of my work. Sometimes, stuff happens, and I can't be sure what the problem might be. Standard advice from support in these case is "pave it" meaning uninstall and reinstall the app to see if that fixes the problem.

Recently, IE7 has been throwning the same Onfolio error message at me every 15 mins or so.

In case you need it, here are the instructions for uninstalling IE7 from Windows XP SP2 from kb 917964:

If Windows XP Service Pack 2 (SP2) is installed on the computer

Reinstall Internet Explorer 7

When Windows XP has been repaired and is running correctly, reinstall Internet Explorer 7. To reinstall Internet Explorer 7, you must have the Internet Explorer 7 installation package. This installation package may still be on the computer from the first time that you installed Internet Explorer 7. Locate the installation package in the folder in which you saved the files.

Note This package may be located in the Temporary Internet Files folder.

If you cannot locate the Internet Explorer 7 installation package, visit the following Microsoft Web site to obtain this package:
http://www.microsoft.com/windows/ie/downloads/default.mspx (http://www.microsoft.com/windows/ie/downloads/default.mspx)
To connect to the Microsoft download site, you must have a functional Web browser. If Internet Explorer 6 does not work on the computer after you uninstall Internet Explorer 7, you cannot download the Internet Explorer 7 installation package. Therefore, you will have to use a computer that has a functional Web browser to download the Internet Explorer 7 installation package. Then, use a shared network drive to install the program from the downloaded installation package on this other computer onto the repaired computer. If you cannot use a shared network for this purpose, copy the Internet Explorer 7 installation package onto a CD on the second computer. Then, use this CD to install Internet Explorer 7 on the first computer.
