PowerPoint - Lock to Remote Presentation Remote

We run presentations using PowerPoint and have a presentation clicker/remote which works fine. The meetings are broadcast through GoToMeeting, which also works fine. The problem is that if I click away from PowerPoint to any other application, the presentation remote stops working because the window focus has changed.

I need to be able to control GoToMeeting (chat, answer questions, adjust webcam settings, start/stop recording, etc.) while the presentation is running and allow the presentation remote to continue changing the slides in the background. This way cues are not missed in the presentation while I am managing the broadcast.

Is there any way to "lock" the presentation remote to the PowerPoint application while it's running, so all input from that one device goes only to PowerPoint, even if it's running in the background? I would not want the mouse and keyboard devices to lock to PowerPoint, just the remote which is an HID device. Are there any third-party tools which may do this?

This is running on a Windows 7 laptop. Thanks in advance.
