There is a problem with the new version (7.1.4.0, installed on host and client): immediately after copying a URL on the host, I get an rfusclient.exe error message with a bug report. The problem occurs with all URLs that are copied.

I suspect it has something to do with this addition:
• Added new clipboard transfer mechanism that supports additional formats such as HTML, RTF, EXCEL, images.

>Could you  send us a screenshot of the error message that you receive?
That'st not possible, because I went back to the previous version.

But here is the content of the bug report I saved:

Thank you for the quick fix: version 7.1.5.0 works fine!
