Hi ghazan,
The important thing is that you are using miranda ng without any message window plugins, like TabSRMM.
I could find the "SRMM" in my database, but i have no entry for "SRMsg", this one does not exist in my database. So, i can only upload my "SRMM" for you.
But a friend of me (who helped me with testing, and the videos i've uploaded) updated to the newest miranda version, for testing if the blinking affects him too.
He has the same behaviour. He de-activated his "TabSRMM" (what he is usual using), and after that he get this "blinking bug" too. If using "TabSRMM", the blinking is non-existent.
But in comparsion to me, the "SRMsg" entry is present in his database. But it seems that "SRMsg" has nothing to do with the blinking, as we both experience the same bug without any message plugin.
