Adobe Photoshop 7

Problem

When the Adobe Photoshop thumbnail/icon shell extension (psicon.dll) is installed, the SmartFTP process hangs (not responding) when files with a .psd extension are displayed in the Transfer Queue.

Cause

psicon.dll's RPC calls cause a dead lock.

Solution

Go to the C:\Program Files\Common Files\Adobe\Shell folder and rename the psicon.dll file to psicon.disable.dll.

• or ignore the crash as it does not crash SmartFTP itself.
