I like Royal TS & TSX very much and use it daily!
Thanks a lot!
we are using IE or Chromium (depending on the plugin) on Windows and we don't have any means to mess with the clipboard there. For example, if you open https://www.google.com (or other web sites) you will find clipboard working just fine - at least it does for me. Why PCVisit doesn't work or what you have to do to make it work in PCVisit using a Chromium engine, you may have to ask the vendor of the web site. All I can say is that we don't have any code which interferes with the clipboard on that level.
What I can suggest is to make sure you run the latest version of Royal TS to avoid any bugs or issues which may be in the Chromium engine we used. We are constantly updating the engine as soon as a new version is released.
