"Cannot save images as JPEG files", "Cannot view source", "Cannot print", and
"Cannot download", are all common problems in IE which are usually cleared up by
purging the TIF cache.
Here's how to purge the cache manually:
From the IE menu, click on Tools > Internet Options. In the General tab click on
the Delete Files in the Temporary Internet files section. You'll be presented
with an option to delete the offline content as well...that helps also. Another
setting to tweak is the amount of disk space allocated to the cache. Click on
the Settings button and change the disk space to 50 MB.
If you want to have this done automatically and your surfing habits are such
that you do not need to reuse the existing files in the TIF folders, you can
configure IE to purge the files whenever IE is closed. To implement this
feature, click on Tools>Internet Options>Advanced [tab]. Scroll down the
Settings to the Security section and enable "Empty Temporary Internet Files
folder when browser is closed".
Enabling this setting does not affect cookies nor does it delete the offline
content.
