I like the improvements to the program & the variety of options. I would like to see the "circle" option with a little more flexibility - right now it is very thick & not practical. I also could not adjust the position of text boxes that were misaligned without deleting and recreating them.

It was a little difficult to navigate at first, but has allowed me to begin to file paper claims with insurance companies for a small medical company. Help was quick when I asked. Alignment is a little off, but it gave me a good, cheap start.

I needed to print but had to wait to get ink for printer. Two days later I couldn't find the document to print and one of the Reps from your company helped me find the documents and I was able to print them. Thank you.
