I have also experienced this problem on one of our computers. We have two facilities that run OpenLP 3.13 on both sites, but only one of them has this problem. It is the newest computer with Windows 11 that has the problem, and it showed up early in Januari, after the 24H2 update was installed on the computer. The other computer runs on Windows 10, and has no problem with this.
I should add that it is just when rightclicking in the service area that it happens, and not when using the context menu in any other area, so it seems probable that it has something do with some specific code for the service menu in connection to the update.
I also should mention that I tried upgrading to 3.16 to see if anything changed, but no luck with that.
