Hi,<br><br>We started using OpenLP earlier this year and it has worked well for us. However, we have had a few issues when a PowerPoint presentation is being used. We have had a couple of times when it has all worked fine when the service was initially opened. However, when we came to run the presentation during the actual service it did not work (we were just left with a blank screen). OpenLP was still running and we were able to go onto the next item in the service. However, the only way we could get the presentation to work was close OpenLP, open it again, reload the service and go to the presentation which then worked. This has happened a few times but there doesn't seem to be an obvious cause for the error. We are running OpenLP on a new Dell Inspiron laptop with Windows 10.<br><br>Does anyone have any ideas as to what is happening? Is there a way of avoiding this issue?<br><br>Any help would be appreciated.<br><br>Best wishes,<br><br>Peter
