Hi, I am also having this problem. I can open some flipcharts by double clicking on them but some will not open, just a blank screen. They all end in .flipchart and are saved to my documents. I am using a mac with version 10.8.3 and activinspire 1.7.58968. This problem only started today. I have tried reinstalling the software and fixing the disk permission. Any ideas?
Thanks.
