Fixed in v1.1.0 - coded around with a try catch statement cross-threaded request from more than one control requesting a hostname for the hosts treenodes. A serious rewrite of httpsessionreconform's class requests would be a better solution.
Installation aborts if users checks "install WinPcap" checkbox if WinPcap is already installed on machine. Preferred solution would be for installer to check for existence of suitable version of WinPcap and if found proceed, if not, install WinPcap.
