Yeah; PSPI has been pretty much broken for over a year now (still works for a few plugins). Your best bet is to use the python plugin Shellout which actually launches an external program like XNView for instance to run the PS plugin desired. This may not really be desireable, but, it works. See thread below for details; again thanks RobA. http://gimpchat.com/viewtopic.php?f=9&t=970
Lyle, I'm tempted to install shellout but when I go to the link above there are 22 pages of comments, problems, tweaking and replacing issues dealing with command lines and still more issues with different systems. Since I'm using XP, Gimp 2.6.11, where do I go to get the right one for my system and what tweaks were finally decided on to make it work right?
