Form building problems.

Thanks for setting up this forum. I am hopeful it will be beneficial for all. I am just setting up my software and have been trying out the form builder part of EMR. I have noticed that the palate window will shrink itself and words appear on top of others at times. This makes it unusable. The only way to "fix" it is to close the MacPractice window and open a new one. Any thoughts on what is happening?
