Hi. I am having problems talking to a cirtain contact in my conversation list. I can recieve messages from her and i get everything she says but she doesn't recieve any of my instatnt messages.
I noticed that when she talkes to me or i talk to her at first it comes up at the bottom with "IMSecure is typing a message..." After thinkin about what the problem could be i thought that this may be the cause. To check i looked it up and found that is was a program that protects your Instant Messaging Program and I think it may be blocking me.

I have:
Microsoft Windows XP Home Edition Service Pack 2
MSN Messenger 6.2.0205
Messenger Plus! 3.25.106
StuffPlug NG 2.0.217
Messenger Discovery v2.6.3 (2634)

It may be blocking me because of one of the addons

I am probably 100% percent wrong, but do you have Spleak installed? IMsecure seems to remind me of it for some reason.

NaStuffPlug Has talkers don't it, but i couldnt talk to her before i had that (Messenger Plus! & Messenger Discovery)

Does this contact have some sort of IM encryption package installed? That is probably what's blocking your messages, as it doesn't recognise they are safe.

Zone alarm suite has this and it seems even when its disabled (the IM part of z.a) it still displays imsecure is typing a msg for a sec.
it may help if she disables IM protection by going

opening the main zone alarm window.
clicking IM Security on the side.
then sliding the protection down to off
then clicking the setting tabs and click the advanced button
untick all of those check boxes then click ok and exit

it should fix it hopefully
