well ,suddenly i have one program (programmed in c# .NET ) have its Arabic text characters detached from each other and have left-to-right reading order. here is a screenshot :

now if you want to see how this window should look see it in the development environment:

you may think this is Visual studio specific problem but that program runs fine and produce proper character display in my other machine

anyone could tell what could be the problem ?

i can confirm that this issue is caused by AVG internet security 2015 (paid) . 2014 version installed on my other computer does NOT cause this problem. not sure about the free version.

uninstalling AVG internet security 2015 DOES solve the problem . disabling AVG internet security 2015 ( by removing the services from windows boot) DOES solve the problem.
