I have recently upgraded from 4.3.x to 5.0.2 beta. Everything seems to work, except the mouse cursor. The moment I do anything on WinSCP (such as changing a folder) the mouse cursor changes to a "busy" icon, which is creating the impression that WinSCP "hung" or is "not responding", however this is not the case - it still works.
This mouse cursor problem wasn't present in version 4.3.x.
I am using Windows 7 64 bit, WinSCP 5.0.2 beta.
I couldn't find any existing bug report for this.
