Hi,
When I'm in PMP on Windows, in catalogue mode, the thumbs in a catalogue all load and everything is great.
However if I switch to Windows Explorer or C1 or Lightroom etc.. then back to PMP, the thumbnails disappear but I can hover over them individually still and then it seems to load everything again which really slows down workflow. Eventually it loads back again (all the thumbs) but it's enough for me to register to mention this.
Is this a bug? If so, happy to expand further.
