Error message: "A script on this page is causing Internet Explorer to run slowly"
In Internet Explorer 3.02, this message box can appear on machines running Windows 95. The version 3.02 browser is specifically looking to see if the script thread has pumped any windows messages in the last five seconds. There is no way to override this time-out period for Internet Explorer 3.02. If you are using an ActiveX control with long blocking operations, that ActiveX control should either employ an event mechanism and return control to the caller or call PeekMessage every five seconds to reset the time-out.
As of Internet Explorer 4.0 and later versions, the time-out is no longer a fixed value based on Windows messages. Internet Explorer now tracks the total number of executed script statements and resets the value each time that a new script execution is started, such as from a timeout or from an event handler, for the current page with the script engine. Internet Explorer displays a "long-running script" dialog box when that value is over a threshold amount. Internet Explorer doesn’t check on each instruction to see if it is over the limit. Periodically the script engine polls Internet Explorer with the number of statements executed and Internet Explorer checks if that is over the limit. Because of this mechanism, it is possible to execute more than the default limit without the dialog if the entire script execution finishes before the script engine polls Internet Explorer.

Let me fix it myselfImportant This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
To change this time-out value in Internet Explorer versions 4.0 through 8, follow these steps:
- Using a Registry Editor such as Regedt32.exe, open this key:HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Styles
Note If the Styles key is not present, create a new key that is called Styles.
- Create a new DWORD value called "MaxScriptStatements" under this key, and set the value to the desired number of script statements. If you are not aure about which value you need to set this to, you can set it to a DWORD value of 0xFFFFFFFF to avoid the dialog box.
Because the Internet Explorer versions 4.0 through 8 time-out is based on the number of script statements that are executed, the time-out dialog box does not display during ActiveX control or database-access delays. Endless loops in script will still be detected.
