Error message (in swedish)
When running the Windows ThinLinc client and Microsoft Excel at the same time Excel displays an error message when the user is dragging and dropping cells. The error says that the clipboard cannot be emptied.
This seems to only occur when working in 64-bit Windows. Furthermore, this only happens when a 32-bit application is monitoring the clipboard while running Excel. Even if it might be a bug with Excel we should investigate if there is a workaround. Maybe a 64-bit version of vncviewer doesn't have this problem.
Interesting links regarding this problem:
We regularly experience this problem on Windows 10 Pro 64-bit with ThinLinc client 4.7.0 and Excel (MS Office 365), although I haven't quite worked out how to make it occur reliably.
It's a fairly frustrating issue for us, so it would be great to resolve.
Can we provide any more information to assist in diagnosis?
