There have been reports that the latest update for Java JRE caused IE to
become very slow on some systems. Check Control Panel> Sun Java or
Add/remove programs to see if you're running JRE 5.0 V6. If the previous
version is still installed you could uninstall 5.0 V6.
Following up on Frank's post...
First, clear the IE cache. IE> Tools> Internet Options> General> Delete
files (and delete offline content when that dialog pops up) And set the size
of the TIF folder to about 50 MB (Settings.)
