Hey!

I am really confused
I have installed Windows Live messenger and Messenger Plus! latest versions at my work PC and uninstalled them several times, because there is a situation,  that some of the sentences I should get just get lost in the outerspace or somewhere.
There have been incidents, that my collegue at the same office says me something and I only get one sentence... And if i ask him/her what this means, he/she asks that didnt I got all the text? Copy-pastes me again everything and then I see, that there is many sentences that I didnt got to read.

I cant understand, is these problems connected using Ctrl+Space and hiding my conversation windows or locking my computer with Windows Key+L so that strangers cant get to my computer while I am away.
I havent noticed, that same problems appear, when I am using my home computer. Ofcourse there I do not use Ctrl+Space and Windows Key+L too. But I refuse to belive, that this could be the case why sentences are lost in the space.
My both PCs are using Windows XP operating system.

I am really grateful if someone could solve the sentence eating mystery
