Hi there,
I hope my post is in the right place and hope that i can get any informations or help from u.
Lately i'm having problems with +Speech script, immediately i have installed on my laptop started acting in a strange manner - my windows chat opening automatically and then some messages appear on that window automatically.
I got scared first, but then i found the source of the problem - is the +Speech script.
I mention that in my other PC everything is fine, except my laptop.
Now i have unistalled but i really want it back coz that was the main fun for me.
Any suggestions, how to get it back without causing me troubles?
Kindly i appreciate any answer.
