I recently got Flash cs4 and when I went to go use it today I noticed that the option to adjust my pen pressure, the drop looking icon, was not on my bar. I am using a Fujitsu tablet PC and this worked fine in with CS3. I am kind of stuck as I need the ability so I can finish my shading. anyone know why it is missing? Could it be that I am running windows 7?
If the same tablet worked with earlier versions of Flash then it is most likely a Windows 7 problem. My Wacom tablet works fine on OS 10.5 with CS4.
I had some problems with Wacom pressure in Photoshop and Flash when CS4 first came out, in Windows XP. I finally solved the problem by uninstalling the Wacom driver and then installing the latest driver, instead of simply installing the new driver over an older one like I normally did. Don't know much about Windows 7, but I'd suggest a similar uninstall/reinstall of the Wacom driver.
I will give that a go and see if it helps.
