System Workbench for STM32

STM32CubeMX 5.0

CubeMX 5.0, (under Eclipse), hangs under the following scenario:

Make a change in CubeMX window, in my case select one pulse timer mode, (see attached screenshot).
Do something else until the Project not saved dialogue box appears, in my case I browsed the internet.
Click on Yes to save and the application hangs.

File/Save from the menu works ok.

Thumbs down for CubeMX 5.0 The GUI is chaotic. It looks like a mobile application. A lot of clicks are needed to open all categories on the left side. The middleware section in the middle does not fit so scrolling is needed. I do not see what the improvement is but if you want to use the latest drivers i guess you need to live with it.
