Abstract

Disclosed is an information processing apparatus for switching a first session and a second session in executing processing, the apparatus comprising: storage controlling means which, if a first module belonging to a group is activated in the first session, then stores correspondence between the first session and the group; and activation controlling means which, if a second module belonging to the group is activated in the second session, then stops activation of the second module based on the stored correspondence between the first session and the group.

Claims

1. An information processing apparatus for switching a first session and a second session in executing processing, said information processing apparatus comprising:

storage controlling means which, if a first module belonging to a group is activated in said first session, then stores correspondence between said first session and said group; and

activation controlling means which, if a second module belonging to said group is activated in said second session, then stops activation of said second module based on the stored correspondence between said first session and said group.

2. An information processing apparatus according to claim 1, wherein, if said first module is activated, said storage controlling means stores correspondence between said first session and said group based on data which are held in said first module and are indicative of said group.

3. An information processing method for use with an information processing apparatus which switches a first session and a second session in executing processing, said information processing method comprising the steps of:

if a first module belonging to a group is activated in said first session, then storing correspondence between said first session and said group; and

if a second module belonging to said group is activated in said second session, then stopping activation of said second module based on the stored correspondence between said first session and said group.

4. A program for use with a computer which controls an information processing apparatus for switching a first session and a second session in executing processing, said program causing said computer to execute the steps of:

if a first module belonging to a group is activated in said first session, then storing correspondence between said first session and said group; and

if a second module belonging to said group is activated in said second session, then stopping activation of said second module based on the stored correspondence between said first session and said group.
