Hello,

I am currently working on a UI for my project in 4.5. But every time i try and open any widget in the editor, the whole editor crashes.

 ![21528-opening+widget.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/f/1/b/f1bb3faf101de8b1f6aefbb07e35cf74226787b2.jpeg)

Any advice or information would be much helpful.

Hello ,

I have a couple of quick questions for you to help narrow down the issue that you may be experiencing.

Quick questions:

1. Can you reproduce this in a clean project?
2. If you can reproduce this in a clean project, can you provide accurate steps to reproduce the issue?
3. Did this issue start to occur after updating the engine? (Example: Update from 4.5.1 to 4.6)
4. Can you provide us with your dxdiag?

Please note: Thank you for the information provided. However, it would be more convenient for us in the future if when you are posting a crash report if you simply copy and paste it into a notepad and attach it to the question.

Hello Triplett,

I can reproduce the issue in 4.5. The crash happens when I reorder the layout, go to the graph, come back to designer and click on one of the widgets.  
Here is the call stack: (Note: Thanks for the heads up, Is there any way you would like this formatted in the future please let me know)

Hello ,

I was unable to reproduce this issue following the steps that were given. Just to be clear, did you mean that you switched up the hierarchy of the widgets when you said “reorder the layout”? When you say that you can reproduce this in 4.5 did you mean 4.5.1?

Hello Triplett,

Yes I am currently working in (4.5.1), sorry for the confusion. Here is the layout that i use that caused the crash:

Hello ,

I am still unable to reproduce this issue. Could you please provide your dxdiag?

To run a dxdiag report follow the steps below:

- If you are running Windows XP or higher go to your task bar.
- Click on, “Start Button”.
- Click on, “Run”.
- In the pop-up window enter dxdiag and hit ok.
- The DirectX Diagnostic Tool pop-up window should appear.
- Click on, “Save all information”.
- Save As" window should be present.
- Click on, “Save” (The file should be saved to your desktop as dxdiag.txt)
- Exit the DirectX Diagnostic Tool.
- Attach the dxdiag.txt to the next reply you make

I have also provided a link to answer your previous question about how to handle crashing in the future.

Here is file you have requested. The crash seems to happen only when i click on a image brush or progress bar, after I have rearranged the layout.

Hello ,

I see that you are working on a laptop. Typically laptops have a harder time running the engine. Could you please take a look and make sure that your laptop is using the Nvidia Graphics card (NVIDIA Quadro 2000M ) and not the on board graphics card (Intel(R) HD Graphics 3000)?
