To get out of an infinite loop:
In Visual Basic, type
     control-break
Then you are in the debugger, and can see where
you are stuck.  Select “continue” to proceed
If a program (any program) gets stuck in Windows, you
can also type control-alt-delete and get a task
manager.  Select the offending task and end it.
Caution: you’ll lose any changes for that program
since the last save.
