Flash CS4 Bug: Clicking the “New library panel” button in the library throw an error message

Posted by Riccardo on April 21, 2009 11:33 pm under Flash

Bug Description
I was working on 2 open documents and I needed to copy a MovieClip from a library to the other. I clicked the “New library panel” button in the library but it throwed the error “Unable to open a new Library Panel. The limit of ten open Library Panels has been reached.”, and my opened Library Panel is only one. Closing and reopening the documents or create a new blank document didn’ fix the problem. So I closed and reopened Flash and it was throwing the same error. Then I closed Flash, Dreamweaver and Photoshop but after reopening Flash was the same situation.

I rebooted the computer but the error persisted. Then I tried to change the workspace and the problem disappeared. Switching back to my personalized profile throw the error.

How To Reproduce
My os is Windows XP SP3 with Flash CS4 Professional (with latest updates). I tried to recreate the same workspace but the error didn’t appear.

Workaround
Select Window -> Workspace -> Reset ‘your workspace name’ in the menù.

This is due to CS4′s workspace being automatically saved while you work. To fix it, go to the app menu Window/Workspace and click on “reset [your workspace].” This method doesn’t require any restart or reboot.

Hi Mike,
I already mentioned the fix in the Workaround section.
Thanks for confirming the solution.

well… as a workaround… ok, it fixes the bug, but it screws up your panel layout

When you personalize a workspace you are supposed to save it using the menu item Window -> Workspace -> New Workspace…so you can re-apply it after resetting the workspace.

THANK YOU for this, I had multiple libraries opening and it was driving me NUTS. So glad people like you are here to help.

Anyone know what to do if the reset has no effect on the bug?
I can’t believe I’m actually unable to open multiple libraries now in a $500 program. And this bug has been around since the beginning of 2009 at least?
Maybe Adobe should start releasing software that works every few years instead of throwing buggy crap out there every 10 months. Capitalist pigs…who else misses Macromedia?
