Hi all experts,

The problem is that when My RAP application is running, the IE often popup a message dialog, and the message in the dialog is:
"A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive." "Do you want to abort the script?"

The IE version I am using is 6.0.
The RAP version I am using is 1.2.0.

The problem cannot be reproduced every time, but frequent.
When this problem occurs, if I choose abort the script, an error dialog just pops up latterly and tells me that "'org' is not defined(line 63)",
otherwise it works fine if I choose not to abort.

Could you please have a glance on this problem?

Thanks and Best Regards!

Hi, lyp.

I've seen this problem in IE 8 (FF doesn't show this message). My solution was to check the checkbox "Don't show this message again" Smile

Hi, Yury.
Thanks for your reply.
But The IE version We used is 6.0, and we cannot force every client to update IE to 8.0.
In IE 6.0, I cannot to find the checkbox "Don't show this message again"

Best Regards!

Hello lyp.

Does ths happen while the browser is loading the application, or later
on while using it? If later on, on what kind of interactions is this
message appearing?

Generally speaking, older IEs are very slow (compared to modern browser)
and produce this messages if a JavaScript call is taking longer than a
few seconds. If you don't choose to abort, everything should still be
running fine.

There are a couple of possible, but not ideal solutions.
The most obvious are: Use a more current browser or use a more current
version of RAP. This might get rid of the problem. If that is not an
option, you might try to optimize your application so that not too much
widgets are created or changed at once. Also, it is possible to change
the timeframe that needs to be exceeded for the message to appear, but
only by editing the windows-registry.

Greetings,
Tim

Thanks a lot.

Hi Ivan,
I will try to install the IE patch according to the FAQ. Then check it.

Hi Tim,
This happen while using the application. The IE will open an information dialog including the message.
And For many reasons, I cannot use a more current browser or use a more current version of RAP in the near future.

Hi,

to be honest, if you don't have the chance for an browser upgrade in the
future, RAP probably might not be the best technology for you. Although
there are examples where RAP apps run on IE6 in an acceptable way, I'm
not sure if you and your customer will be happy with that in the long term.

Regards,
Stefan.

Not to be nit picky or eny thing but the text

http: //wiki.eclipse.org/RAP/FAQ#Why_is_IE6_so_slow.3F_What_can_be _done.3F

Why is IE6 so slow? What can be done?
The JScript engine used in Internet Explorer 6 - Microsoft Windows Script 5.7 - is known for being slow with AJAX applications. The solutions, suggested by Microsoft are:

if you can upgrade to Microsoft Windows Script 5.7 - apply hotfix 919237;
if you have to stay with Microsoft Windows Script 5.6 - apply hotfix 942840 which includes an improved garbage collector.

For more informations on this topic, please take a look at the following links:

Seems of seeing that they want to upgrade to 5.6 shouldn't it be then:
