I also posted this in Numerix's forum but I am sure he/she is busy so I am hoping perhaps another Zenner has some insight.

I recently installed the Barcodes on Packing Slips module to a 1.3.8 site, and made sure I had the latest version download from the author's site. I also followed his advice on making the mode "html".

However, when the image for any barcode displays, it is just a skinny image that looks like a "squished" barcode. It is obviously not the right image being generated, since it looks the same no matter what numbers I enter in the barcode field of the product edit screen.

Anyone else ever experienced this and have ideas what settings or install files I should check out?
