VideoPsalm has PowerPoint issues under some circumstances.

To reduce the issues, you can try the following:

1. Use PowerPoint 2010 or higher.

2. Before starting VideoPsalm, make sure that all PowerPoint instances are closed.

It is a good idea to check with the Windows Task Manager and force-close PowerPnt.exe.

(Sometimes PowerPoint keeps opened, even when there is no PowerPoint window in the task bar).

3. Refrain from using looping PowerPoint presentations.

4. While controlling a PowerPoint presentation, try not to click on the presentation window, so as to not give the focus to this window.
