Back again with some info on my projects loading. That has to do with my chrome cache. I refreshed and deleted all history and then it was OK... I was working in 3 instances in the same browser session. Somewhere it did not want to refresh my list?
Other strange aspect. I have the pro version of zoomify and created two projects (see zip files). The doorwerth map appears in my project, but the geelkercken map does not?
Any idea? http://www.heemkunderenkum.nl/download/geelkercken1660.zip and http://www.heemkunderenkum.nl/download/doorwerth1868.zip
Below the downloads as zip.... Will also try in Safari and Firefox of course
