I have been using the current version 2.9.1 without any issues, until yesterday. After importing a .zip, orienting it to best printable layout, hollowing it with a 8mm drainage hole on the bottom, and then automatically generating support structures at 100%, the program hangs up in slicing process at 14%. This is constantly happening. After trying to hit escape it will give me the "(Not Responding)" title at the top of the page.

Can you please make any suggestions?

Thank you,
Pam Timm
