I found the solution in the forums to slow win7/vista performance that worked for me.
On the client side right click the UVNC connection icon and deselect

Re: SecureVNCPlugin64.dsm
I have tried to rename SecureVNCPlugin64.dsm to mrsrc4plugin.dsm but I still can not make it work.
Can anyone that has configured the newer dsm's to work using the renaming technique please provide me with some step by step instructions on how to?
Thanks in advance
