Saved projects are missing / not present due to Antivirus Software
Symptoms:
You can import, design and save, and T3RRA Design Plus appears to save successfully, but the save file is not present when you check the save location. In addition, the T3RRA Design Plus windows are surrounded by a green border.
Cause:
Comodo Antivirus is sandboxing T3RRA Design.
Solutions:
It may be necessary to switch to another version of antivirus software, or to add an exclusion for the T3RRA Design Plus folder. Most reputable antivirus software providers provide instructions on how to add an exclusion. See the links in the previous entry for more information.
