(Part of?) the solution was to upgrade the files in ./libs/ to Syncfusion 17 files.

Qiqqa Logging for SF 17 (SF 14 **hangs inside that SF.Pdf API call!)

**Warning**: I got those files by copying a Syncfusion install directory into qiqqa::/libs/ and overwriting existing files. v17 has a few more files, but those seem not to be required/used by Qiqqa, as **only overwriting what was already there** in the **Qiqqa** install directory seems to deliver a working Qiqqa tool. :phew:

Closing and decluttering the issue list so it stays workable for me: fixed in https://github.com/GerHobbelt/qiqqa-open-source mainline=master branch, pending #15 / any maintainer rights/actions.
