Limitations

The Sun Java is configured to allocate a small memory size for Applets, so it is not advisable to use the editor for files of more than 10,000 individual lines or if the sum of the number of lines in edited files is more than 20,000. To overcome this limitation increase the memory available to Applets in the Java control panel.

Known Bugs

If the line grow above the current maximum size, the scroll bar are not always properly updated.
