Hey Selahgal - It's not unusual to get script errors in I.E., a little more rare in Firefox and quite unusual to get them in both.

When dealing with browsers it always helps for us to know which version you are using, in future could you please post that information....t'would be much appreciated.

Here are the common fixes:
In Internet Explorer: Firstly, remove/delete all temporary internet files. Now go to; [b:31gtnxdt]ToolsInternet options[/b:31gtnxdt] and click on the [b:31gtnxdt]Advanced [/b:31gtnxdt]tab. Under 'Browsing' place a checkmark in the box next to..'Disable Script debugging (other)'. Make sure there is [b:31gtnxdt]not[/b:31gtnxdt] a checkmark in the box next to...'Display a notification about every script error'. If there is a checkmark in that box, remove it.

In Firefox: Most likely cause here is an incompatible add-on. Try disabling each add-on, one at a time, until the errors stop and that will tell you which one is causing the problem. Then either leave it disabled or uninstall it.
If that is not the problem please do this; Open Firefox and in the 'Address Bar' (not the search bar) type in [b:31gtnxdt]about:config[/b:31gtnxdt] and then hit 'Enter'. You will get a message about voiding warranty, just ignore that and click on the 'I'll be careful' button to continue. Scroll down until you locate this entry: [b:31gtnxdt]dom.max_chrome_script_run_time[/b:31gtnxdt]. To the right of that, under [b:31gtnxdt]Value[/b:31gtnxdt], will be a number. Please let us know what that is.

It still worries me that you are getting script error messages in both browsers, that points to the possibility of a common issue outside of each browser's own settings....maybe just coincidence. Dave and Ziggie will have some better ideas on that.

In the meantime, please try the above and post back with the results....hopefully that will fix it.

cheers now....JIM
