Anybody else seen this problem in Flash 8?

Create a new document. Import a bitmap image to the library. Right click it in the library, select Export for Actionscript, and give it a linkage ID ("image");

Then delete the image from the library. Import a new bitmap image, and give it the same linkage ID as before - Flash throws an error "You must specify a unique identifier to export or import this symbol" - even though the new image is the only thing in the library...

Argh...
