I can see the window fine and if open another session to the same host, i can see my old
session on remote host (with command w).<br><br>I am guessing ti is because of limited RAM, but I am not sure. I do not run any server App or big script program etc. on this VM, mainly for ssh into remote hosts and run a few small scripts here and there.<br><br><br><br>Win7 (host) details from Performance Monitor:<br><br>___with normal apps running on win7 and nothing unusual running on ubuntu_VM___<br><br>used physical memory: 74%<br><br>Installed: 4096MB<br>Total: 4046MB<br>Available: 1005MB<br>Cached: 984MB<br><br>HW reserve: 50MB<br>In use: 3040MB<br>modified: 2MB<br>standby:
