Keeping menu tree form session connected to DB, while other forms are open

Question

When our application starts, a menu tree module is opened, which contains a list of modules that users can open. When a user click on a module to open, the code will issue the command open_form (…,…., session). So every form is opened in its own session. The maximum idle time allowed in a session is 45 minutes. Therefore after setting idle for more than 45 minutes any module including menu tree module will lose connection to the database. So if a user open a module from the menu tree module and spend more than 45 minutes working on that module, when the user go back to the menu tree module, they get an error that menu tree module lost connection to the database. So the question is, how to keep the menu tree module session connected to the database, even if it exceed the maximum idle time as long as other modules sessions are still connected to the database.
1. set maximum idle time allowed in the database for 5 minutes
2. open form A
3. open form B from form A in it own session (OPEN_FORM (...,...,SESSION)
4. work on form B for more than 5 minutes
5. go back to form A,
6. fom A has been disconnected from the database
I have tried to use the timer, but the problem with timer is when a timers fire in forms that
do not currently have focus, and a context switch is performed. The form flickers when the context switch is made, and the current item text becomes selected when focus returns to the
current form, which will cause problem to the users.
Our client setup the database timeout for security reason, and therefore, it cannot be replaced by TIMEOUT PJC.
Keep in mind that we have 600 forms and the application is already in production.
Thanks

Thank you Manu
I added the following code logic to when-window-activated
if menu-tree still connect to the DB then
do nothing
elsif lost of connection is due to exceeded maximum idle time then
if the global.last_closed_forms_transaction < 45 minutes
or if there is form that is still connected to DB then
logout;
login;
else
messagebox ( exceeded maximum ideal time allowed )
end if;
else
messagebox ( lost connection due to network error)
end if;
Thanks
