I use barcodes extensively to automate forms, and the update to 10.1.0 broke the ability to use Code 39 barcodes. The font now displays a few lines of barcodes and a series of squares where the rest of the barcode should be. Interestingly, static barcodes appear to be fine, but dynamically generated barcodes fail 100% of the time after updating to 10.1.0.
I've developed an uninstall/reinstall package to move our 367 PCs back to 10.0.1, and this has solved the problem. The issue is also occurring on Acrobat X when users upgrade to 10.1.0.
Is there a known workaround? Has anyone else experienced this issue? I hate to keep our users on old versions, but I'll be holding off on allowing Reader/Acrobat updates until I have a fix.
