Important Note (updated):
After testing Mold Tooling ST with the Maintenance Pack 3 (MP3) for Solid Edge we recognized some hangs inside several Mold Tooling commands. At that moment, it is only possible to terminate the Edge.exe process while loosing all changes made since the last save. The problem was caused by a user interface code change in Solid Edge, which expected a specific control which does not exist on some of our commands. Therefore, we do not recommend to install MP3 for SolidEdge ST together with Mold Tooling ST to avoid data loss. You should either roll back to an earlier Solid Edge maintenance pack or install MP4, where this problem was addressed.

We could verify that Solid Edge ST with MP4 does no longer show this problem and recommend the installation of MP4 when working with Solid Edge ST and Solid Edge Mold Tooling.
