The only issue that I know of is related to Icons in the Library not displaying, but the Mouse Over still works, so you can figure out where you want to go...

The other issue is related to permissions and only affects Activation.

1. BEFORE launching your freshly-installed copy of Poser (Debut, Poser 8 or Pro 2010), browse into the root Library/Application Support folder and create a folder for your copy of Poser- 'Poser', 'Poser Pro', or 'Poser Debut'. You'll need to provide an admin password to do this.

2. Launch and serialize Poser normally- you won't be able to see the category icons in the library pane but the mouseover category names should work.

 

1a. If you have launched Poser and entered a serial number and are now seeing Poser crash on launch, the first thing to do is to open System Preferences, go to the General pane and turn off the 'launch to previous state' option.

2a. Now go create the 'Poser', 'Poser Pro' or 'Poser Debut' folder as described in (1) above

3a. Launch and serialize Poser

4a. Now if you like you can reactivate Lion's 'launch to previous state' option. 

Anyone that encounters other issues, please contact Support with details. Put Attn: John, Lion Issue in the Subject.

Thanks
