Hi DZ,

This is a known issue and is caused by the cache filling up when you open a
lot of tabs/windows. You can either close some tabs or Clean your cache
occasionally from the options on Internet Options. See Tools>Internet
Options - General tab, Temporary Internet Files section - Settings button.

Use the recommended settings for the cache size This may not prevent it from
happening again when you have a lot of tabs/windows open.

Regards.
