BEWARE Studio 2.26.7_1
Problems with the lastest include:
* Continued inability to copy / paste submodels with 3+ levels of nesting between files - typically results in a crash.
* Import file seems to fail randomly if there is anything more than one submodel being imported.
* Submodel corruption in the editor <- worst problem yet. Submodel changes are randomly not saving correctly, and many edits turn the model into the dreaded black box w/. '?'.
If you value your time, stick with version 2.26.4_1.
