If you haven't upgraded to 7.8 yet, here's a summary of the EFS bug fixes for this release listed by our internal EDL case numbers.
EDL34 - Fixed a calculation error and added the ability to use either standard deviation or standard error in the calculation of the channels for a Linear Regression study on the advanced charts.
EDL35 - The Linear Regression study was also using the wrong set of bars for it's calculation. It was off by 1 bar and is now corrected.
EDL107 - Fuchsia was spelled incorrectly in the formula script (Color object) and with the formula wizard which caused an error in the code. This has been corrected.
EDL412 - Objects in formula script were drifting on tick charts and should now hold.
EDL588 - The setBarBgColor() EFS function was covering up drawn lines and gridlines even when you set the drawn lines to always be on top.
The gridlines are still being covered. Our developers know this. The mention of gridlines in the readme.txt file is an error.
