I recently upgraded to Windows Vista and Adobe CS3. I've found that if Particular has more presets than can be shown from the dropdown menu, the menu opens on the taskbar instead of the presets being pushed to a second column. I've reinstalled Particular but it's still having a problem.
Is this a problem within Particular or After Effects? Btw, I did install Adobe CS3 after I had installed Vista.
I just figured out that this is a problem with After Effects CS3. I copied and pasted multiple presets for another plug-in and it had the same problem after I filled the presets folder with more presets than AE can show in one column.
I don't know if this is specific to only my installation of AE CS3 or if it applies to every copy.
