how do i close LO?

I keep getting a message about some program that is running, asking if I want to close it. At the same time, my computer slows to a slow crawl. When I check the Task Manager (Win 7), it shows eight or ten instances of LO running. When I stop them with TM, the problem stops.
I close documents with Alt-F Alt-C, and close the main window of LO with Ctrl-Q. What am I missing?

Kill the following to ensure it’s closed:

  • soffice.exe

  • soffice.bin

Your computer can’t be working right.

This is the only program with this problem. This problem is still occurring. Why should I have to close LO with Task Manager?
