The developer responded to an issue we were experiencing with 2.1.1 and 2.1.2 in OS 10.3 and 10.3.1, and responded immediately by sending a beta version of 2.1.3. We were so impressed by the response that we purchased two licenses prior to the fix. The program is fully operational and unlike other program plotters, it's simple to use and in minutes we had several development program's schedules ready for customer proposals and presentations. The export to JPEG, TIFF and PDF is flawless, and makes embedding into large Word, PPT and/or PDF documents simple. We highly recommend the product and the developer.
