On Monday, we released a patched version of Qube! 6.9-0, labeled as 6.9-0a, which contained a fix for thumbnails and image preview in ArtistView.
Today, on Wednesday, we subsequently released another patched version of Qube!, labeled as 6.9-0b, which contains a fix for qbping which could have affected users as early as Qube! installation.
If any further issues are seen, please do contact support and let us know right away.
We strongly encourage the downloading and use of the latest patched version. The manifests and release docs have been updated accordingly.
Thanks!
