Have problem locating plug-ins

[ajax]

Yes I do know about the current directory.  In fact, the scripts I use for starting the applications that I've setup on a portable drive always set it to something useful.  Since I don't know how GIMP might rely on the current directory I set it to the same folder as the file used to invoke GIMP.

It looks like GIMP does do something special (i.e., not done by other Windows software) when it comes to identifying the drive where the application was loaded from.  This is possible and something that I rely on very heavily to make my executable software function properly.

Thanks again for all your help.
