I use internet explorer on one pc and google chrome on another. Its the same problem on both browsers. I noticed this a few month back when edaboard website was hacked and a notice showed stating "cosed for maintainance" showed on main page. I was online at that time. I could not log into after that. I have to re install windows because i could not fix it.I thought, the hacker may have reached user's computers. Is it possible? On one computer , if i deny the leave page message, it is posted once. I have to click 'go back' and then ' refresh page' to see posting. If i click leave page, it is doubled posting. I often edit and delete manually to look it clean. On other pc, with "chrome", i have to click ok. Somtime it is single posting with a notification about new posting in thread. When i open, it shows "me", who have posted a new post in subscribed thread.
I have received some five messages about a thread deletion notice from 'gulson' within last two months but the thread is still there.
