Thanks I downloaded Chrome as my PC was using IE 10 & suddenly Planefinder stopped working. The site is excellent especially for elderly guys like me who can no longer travel out to airports to spot aircraft. The only drawback since I use Chrome, is a load of pop-up ads which I never got when using IE10; in fact it was working perfectly before.
Sorry for dropping IE10 support. If you are on Windows 8 I believe you could upgrade to IE11 but even this browser is only getting security updates now by Microsoft.
We like to push the boundaries with technology. With only 0.2% of our user base on IE10 it was sadly time to drop it as it didn't support some of the stuff we were doing. We also saw that users had a workaround of Chrome or Firefox.
