We are working with TightVNC as part of our work flow,
Server machine : win . xp ( 32bit)
Client: win. 7 64bit
VNC server - 2.7.10.
After working for a few days we are having responsive problem, and cannot work ( we get slow user and ux issues on the remote machine ).
Once we reconnect to the same machine with RDP we have not problem working with the window .
