My experience with Zonealarm as follows. When Zonealarm upgraded to version 2.1.44 it failed to correctly interact or recognise Ping Plotter even though the prior version had worked properly. I use Win95 OSR2B and for some other reasons I upgraded from Sockets 1.1 to Sockets 2.? and low and behold Ping Plotter was once again recognised properly. My experience concurs with something I read which is that from Zonealarm version 2.1.44 it went fully with the later sockets ( 2.? ) which is also the same as used in later WinX flavours. <br><br>
