l think I may have found what causes the top of the project in EZ Builder to be cut off and hidden under the top menu bar for some of the users of EZ Builder. I noticed that this problem has continued for me but seemed to happen randomly. The only way to fix the problem once it happened was to do a "Smart Arrange" in the control tab and loosing all my custom placements of the controlls. After months of watching this behavior and the frustration it causes I noticed that it seemed to happen only when I saved my project after I did some new work to it. Then I noticed that it seemed to only happen when I saved the project and the window was scrolled down towards or at the bottom of the project page (or even to the side) and then exited to Windows. The next time I opened EZ Builder to this project it would be as I saved it; the top or side hidden under the menu bar or side but now with no way to scroll up or to the side to get there.
I started to scrolled to the top left of the entire project page and then save and exit. This seems to be a work around to this problem
So now each time I save and exit my EZ Builder project I need to make sure I'm scrolled to the top left of the entire project page. This way I never seem to have the top cut off and hidden under the menu bar and no need to auto arrange and loose my custom placement of the controls.
I've been doing this for several days now and seems to be working. I don't know if the EZ Robot team can check this out and fix it because they have not been able to reproduce this problem on their system.
Hope this helps others. Have fun!
