VP-UML 5.2 GUI frozen after deleting a shape in class diagram

I have encountered the problem, if deleting a class from a class diagram, the GUI get frozen. No way to add / move or do anything. Just closing is possible. Then I’m asked if I want to save the project. This does not happen in other diagrams like use case diagram.

I have uninstalled and installed again. We are using several licenses for build (Build 20060214) Currently this hinders us from making our design in current project!
How can this version can go through QA?

Dear Frank,

I am very, very sorry for any inconvenience this problem may cause you. Would you mind sending me the vp.log file to have a look? You can find it under %VP_Suite_Installation_DIR%/bin

Secondly, is the problem repeatable with your project? If yes, could you please also send me the project file for testing? You can reach me at:

Meanwhile, I would recommend you try our latest release which may include the fix of this problem. Here is the hotfix of the latest build:
