We are having trouble with On-Screen keyboard and latest Flippingbook Publisher 2021.1 catalogue. Link to catalogue
https://www.wuerth.ee/kataloog/index.html. There is a search function in upper right corner. Clicking on search will open On-Screen keyboard only once, if you close it, it will not appear again. It was working with previous version of Flippingbook. We are using Chrome browser engine. On-Screen keyboard works with IE engine, but then is there other problems with: animations, double click zoom, clicking links in table of contents.
