Managing Pop-up Messages
Under various circumstances, an Internet Explorer pop-up window: "A script on this page is causing Internet Explorer to run slowly" is displayed when the number of script statements being executed is more than the system default. The user can either select Yes to terminate the script or No to continue.
Firefox can display the pop-up window: "Warning: Unresponsive script A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete."
These messages can appear multiple times depending on the content of the page being loaded and most frequently when rendering large tables containing thousands of CAD Documents and/or WTParts. Display of a large workspace or an add to workspace collection page are typical operations where this issue would occur.
This section lists methods for managing these pop-up messages
.For Internet Explorer:
As a temporary solution, select "No" to the script cancel requests until the page appears or limit the number of objects in the workspace or preferences screen by changing the Collection Rules for that page.
As a permanent solution, open Internet Explorer, select > and choose the Advanced tab. Under the Browsing heading select the Disable script debugging entries and deselect Display a notification about every script error. In addition, see http://support.microsoft.com/default.aspx?scid=kb;en-us;Q175500 about adding a registry entry to change the system default script execution limit for the warning message.
Excerpt from Microsoft document:
1. Using a Registry Editor such as Regedt32.exe, open this key: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Styles
 |
If the Styles key is not present, create a new key that is called Styles.
|
2. Create a new DWORD value called "MaxScriptStatements" under this key and set the value to the desired number of script statements.
A MaxScriptStatements value of 0xffffffff (Hexadecimal) or 4294967295 (Binary) seems to work best for Technical Support.
Shut down Internet Explorer and Windchill Workgroup Manager and restart Windchill Workgroup Manager.
For Firefox:
As a temporary solution, select Continue to the Unresponsive script messages until the page appears or limit the number of objects in the workspace or collection dialog by changing the Collection Rules for that page.
As a permanent solution, enter "about:config" in the URL location field of the browser, search for the "dom.max_script_run_time" preference and increase the preference to a higher value, say, 30 or 60.
