Google Chrome Freezes Windows 7 on Tab Close
Symptom Tabs that have been idle for some time (swapped out?) cannot be closed without locking up Windows 7 (freezing of cursor and keyboard) for almost 45 seconds. The Windows swap space was set to be self-managed by Windows, and was set to 16GB. More recently used tabs could be closed without difficulty. Further, even tabs that showed difficulties closing could be activated and browsed normally without latency.
Update 12 July 2013 This appeared to be caused by Windows 7 not having enough swap space. New setting shown below.
