Display problems

Greetings All
Have been using planefinder for quite sometime now and have enjoyed no problems untill just recently when I had to have my hard drive replaced. Since then I cannot use planefinder as I now have the situation where Australia is satuated with a/c that are supposively traversing the US. I do have a laptop which is operating correctly
Any help will be greatfully received
Hi Lee and thanks.
I realize this next part will seem crazy to most on the forum you have to realize that what you have on this key board is an old fart who is to a certain extent computer iliterate so things I say computer wise may be double dutch and may not make sense to those in the know
Question! other than the clock situated on/in the task bar on the left hand bottom corner of the screen which is in my case set to Adelaide Sth Aust time (CST) is there any other clock that needs to be set and if so where and how
Not the same problem but I also had my hard drive replaced recently, had to re-install loads of software including IE9. Having finally got the PC running somewhere near its previous state I found planefinder refusing to work with just a blank map and the time 00.00. Flightradar24 had the same problem. Using Google Chrome I found both planefinder and flightradar working normally. I eventually solved it after experimenting with IE9 settings and concluded it was caused by Tracking Protection which was set to ON. It's now set to OFF which has eliminated the problem.
