since version 3.6 and with version 4.0 beta, i have problems when running the Dude, my networkcard of my pc (runing VMWARE Client) looses contact to my vmware ESX 4.0U2 server. as soon i start the dude, it takes a while then connections to the ESX are not possible any more. with a restart of the pc, everything is fine, i can use winbox ect. but as soon i start the dude, after a short time (maybe 10min) the connection to my ESX is broken and will not work any more.. (till a reboot)
