This issue has been addressed in the form of a registry key fix in Internet Explorer 5.01 Service Pack 1 (SP1) and in later versions. If you are running an earlier version of Internet Explorer, you must first obtain and install Internet Explorer 5.01 SP1 or a later version. Then, you must turn on the fix.
To configure Internet Explorer 5.01 SP1 or a later version to exceed the 4,000-character limit, you must create the MaxRenderLine registry entry with a DWORD value that is larger than 4,000 to turn on the fix. To do this, follow these steps:
Quit Internet Explorer.
Click Start, click Run, type regedit, and then click OK.
Right-click Main, point to New, and then click DWORD Value.
Type MaxRenderLine, and then press ENTER.
Right-click MaxRenderLine, and then click Modify.
Under Base, click Decimal. In the Value data box, type the number that you want to set the limit to. For example, type 4100. Under Base, click Hexidecimal to convert the number to the default hexidecimal value, and then click OK.
In this example, you typed 4100 (decimal) to set this value to 1004 (hexidecimal).
Close Registry Editor.
