Where did you get 2.0b9? The download page still shows 2.0b8 as the current beta?

" Download 2.0 Beta 9 (18 May 2013)"
Force refresh the page, perhaps? (cache issue?)
I hadn't noticed the update too, anyway, thanks for the info, Alex!

Yep, that did it.

Downloaded 2.0b9 and unzipped it.
Works fine, except the console colors are back to default (I had dark red text on black background! Unreadable for me, bad old eyes...)
Tried to install the JS mode, got a socket connection error.

Closed the PDE, did something else, ran the PDE for further help on the forum, tried again, got the error:

Ie. basically the same messages...
Not sure what to do now, except opening a new bug on GitHub, I fear...

About the theme: there is no longer a theme.txt file in the processing-2.0b9/modes/java/theme folder, but copying the one from 2.0b8 (changed to my preferences, previously) fixed the issue.

Positive note: startup of the PDE and spawning a new window are now dramatically faster than in the previous version!

Negative note: some changes (from previous versions, actually) annoy me:
- When I loaded a sketch via the toolbar button, it was opened in the current window, now it always open a new window and I have to close the old one. Idem for the New Sketch button.
- When a sketch is running and I click the Run button, it doesn't stop the current one and run a new one, as before. I have to click Stop then Run for that. Why these extra operations?

Apparently, there is a workaround for this annoyance: I tried to delete the tmp folder created in the modes folder (see the above messages), and I was notified it was locked.
So I closed the PDE, and I moved the JavaScriptMode folder inside the tmp folder to the upper level (ie. in the modes folder), then I deleted the tmp folder.
Starting the PDE again, I had the JS mode...
I will open a bug, it looks like there is some kind of lock to remove internally before cleaning up.

[EDIT] Used an existing recent bug: https://github.com/processing/processing/issues/1781

The correct way would be to install it manually. Remove all instances of the broken mode, download "latest" from my repo (which is what is being installed by the manager), unzip and put it into modes. Restart Processing and it should work.

Thank you,  fjenett!

Thanks fjenett,

You can find download links for other modes here

Hi, I'm new.
I just downloaded and installed latest Processing 2.0, never have Processing before. I need it for a Coursera course.
Then I follow instructions from the Coursera's video, to add mode (android and javascript) from within Processing.
Did not work.

(WIndows XP SP3, Java 1.7)

I found this thread, followed instructions in here.
Deleted all the tmp modes folders.
Downloaded the modes from the link above. Unzip and copied AndroidMode and JavaScriptMode folders into processing-2.0/modes/ folder.
Then re-run Processing. Unfortunately it did not work. Still no android and javascript mode in the Processing. (only java and experimental)

THen, I deleted all processing folders, they are: the main Processing application folder, the folder in My Documents (with the tmp), and the folder in C:\Documents and Settings\USER_NAME\Application Data\ (with the preferences.txt)
Cleared Java cache.

Then, reinstalled (unzip) the latest Processing package.
Copied the AndroidMode and JavaScriptMode folders into processing-2.0/modes/ folder.
Run Processing, still no android mode, no javascript mode.

Is this because I install a brand new Processing, and never have Processing before?
Is there something I need to edit to be able to add the android and javascript mode manually?

Thank you in advanced for any responses.

Strange it worked alright for me. Both in Linux & Windows! These modes -> CoffeeScript & JavaScript
