How to Stop the annoying script alert if using FIREFOX browser:

Open up a text editor such as Notepad and browse to the a file named "all.js".
c:/Program Files/Mozilla Firefox/greprefs/all.js (yes, open the file).
About 995 lines down you will see the following command lines:

pref("dom.max_chrome_script_run_time", 20);
pref("dom.max_script_run_time", 10);

Change the values in each line to a higher value. I use 2000. Also add a comment behind the command lines (including the backslashes) about your modifications (just good practice).
Any text after the // is identified by the // as a comment and not part of the command line.
My changes look like this:

pref("dom.max_chrome_script_run_time", 2000); //modified for javatc, default=20
pref("dom.max_script_run_time", 2000); //modified for javatc, default=10

Now save the file. Presto-Chango, no more script alerts with Firefox!
Have fun.

How to Stop the annoying script alert if using INTERNET EXPLORER browser:

Internet Explorer requires a registry setting or change and is a little more difficult than Firefox.
Click the START button at the bottom left of your window and mouse over to the RUN icon. Click it.
A command line input box will appear. Type regedit and click ok.
The registry editor will now appear.
Browse to the following:
HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Styles/MaxScriptStatements (double-click on MaxScriptStatements).
Click on decimal and enter 500000000 then click OK.

Now, if you can't find the Styles folder, then you will need to create it.
Browse to: HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/    and Right-Click on Internet Explorer folder.
A popup box will appear. Browse over to New and click on Key. This will create a new key. Name it the new key Styles.
Now, Right-Click over the new folder Styles. When the popup box appears, browse to New and click on DWORD value.
Name the DWORD value MaxScriptStatements<>.
Double-click on MaxScriptStatments.
Click on decimal and enter 500000000 then click OK.

Now close the Registry Editor and restart your computer. Internet Explorer should not pop up the annoying alert message any longer.
But WOW, what a lot of work. Luckily, you only have to do this once.
Wasn't that fun!
