@petep - Does this happen in the v2.4 release?

[petep]

Sorry I haven't tried that. 2.3.3 is the default package supplied with Fedora 26:

# cat /etc/redhat-release 
Fedora release 26 (Twenty Six)
# dnf list openshot

Available Packages
openshot.noarch                   2.3.3-1.fc26                    rpmfusion-free

It's supplied by the RPMfusion project.

@petep - No problem. I can try on Fedora 26 with v2.4.

[petep]

RPMfusion upgraded to 2.4 today and so far it seems to be much more stable and have fixed the original problem. I'll report again in a few days once we've used it a bit more.

[petep]

All looks great since the upgrade to 2.4. Thanks for your help!

[DylanC]

@petep - Sounds good. Thanks for getting back to me.
