More Information

Even if you have this hotfix installed, you may still receive a similar error message when you use the Cut command or the Copy command on a large amount of text if the available memory is insufficient. However, the hotfix guarantees that Visual Studio 2010 checks the available memory before reporting the error. After you install the hofix, the frequency in which you receive the error message decreases significantly.
