Suddenly losing control of secondary PC
Hi
I am controlling 5 PCs and it works perfectly for weeks then today I go to control a PC and cannot click within a secondary PC then I find that none of PCs are controllable even clicking send ctrl alt del to remote pc did not do anything , I rebooted the master PC and it worked for a while and the it went again , I did try changing firewall setting to resolve but this did not work and anyway had not changed them before it stopped working
Ideas appreciated really really annoying "feature"!
