A word of caution to anyone with the Hightower/SWK Multi-Bin enhancement using lot costing who is considering an upgrade to 4.4/4.5. There are multiple issues with the program that prevent it from functioning properly. We have identified them for SWK and they have been working on a resolution. I don't know if these issues are confined to lot items only or not. If an upgrade is in your client plans my advice is to hold until this is resolved.
