Question

isodraw 7.3to7.4 freezes 4 mns when opening an existing small iso file from fileserver or local HD

Hello,

computer is wire connected to a LAN without full internet access, only some streams are opened (email, microsoft 365 streams but not any any streams)

node locked license on local hard drive
once the file is opened, user can work correctly, no latencies
my question: is isodraw attempting to reach a ptc server when it detects a network connection?
it's not an antivirus issue regarding file extensions, we are able to open quickly *.iso *.cgm *.idr with a text editor.
before analysing network streams out going from computer do you have any clues?
same behaviour for all isodraw computers of network.
i would appreciate some ideas to diagnose

thanks.

SB

hello,

i just need to know if isodraw is attempting to connect to internet as soon as it detects a network connection and which ips and ports. it would have no reason to do it, client is using a local nodelocked license.
our latencies do not occur if computer is disconnected from LAN.

 

Stephan.
