The application freezes/becomes unresponsive. Recovers if I attempt to close the application via the Qiqqa icon on the taskbar (close all windows).

Which version are you running, by the way?

Looks like you're running one of the experimental v83 releases. As a work-around you might be best served with installing the last v82 release and trying again.

Hi,

Yes, running v83. I'll revert to v 82 until this issue is resolved.

Cheers, Vernon

Same issue for v83s, full error info follows; this is from opening a PDF in the library, doing nothing else.
