Can i disable readtimeout

Hello, there two windows specifically I do not want users to get automatically logged out of. I was wondering if there was a way to disable the read timeout for those two windows to enable staying logged on. all other windows have will log out the user after 3 minutes. but I need these two to stay on for a 12 hour shift if need be .

system.nav.getCurrentWindow()

Are you currently using a Client Event Timer Script to check for inactivity?
You could write an if statement that evaluates the user inactivity > 3 minutes and also checks if they are not on those 2 windows, and signs them out if those 3 checks are passed. Similar to the code snippet at the bottom of the getCurrentWindow() documentation.
