I'm running the latest stable Chrome version and have installed the latest "Nitro PDF Creator" that allows me to print to a "Nitro PDF printer" that creates a PDF file of the output. Nitro can also act as a PDF reader with the additional ability of commenting PDF files. Under the 3.xx sandboxie versions there was never a problem. Under any of the 4.xx sandboxie versions I get the message "SBIE 2335 Initialization failed for process symerr.exe [33 / 5 ]" when attempting to print to a PDF file within Chrome. Have gone back to the last 3.xx sandboxie version.
