I used to chat online quite a lot. But it is only yesterday I found a "glitch". I am sure that wasn't always there.
I was exchanging some files with a Windows user, using Kopete. I received his with no problems but he never saw mine offered???
Then I switched to Pidgin and later to Jitsi. NON of these was able to send files! That is to say, at my end all looked normal (file offered) but the other party running Windows never saw the "accept" option.
Anyone can confirm this? Is this solvable?
