OnShift/Alt/ControlDown = crash


I am using the 4.8.2 and I override the OnPreviewKeyDown in my widget.
It crashes when I check if Left/Right Alt/Shift/Control is down it crashes without any “error report” window. But if I just check the key everything works fine.

Any workaround ?

Hey rXp,

I’ve assigned someone to look into this for you, and they’ll post here if they have any questions for you.

It may be helpful to get ahold of the crash log from the project after this occurs. Please reproduce the crash and then find the log in your project’s Saved\Logs folder, then zip and attach it here. Thanks!

Hello rXp,

I was able to reproduce this issue on our end. After a bit of digging I found that this is a known issue (UE-17122) and that it has been resolved internally. This solution will be available in a later release of the engine. I do not currently have a workaround for this issue. You will be able to find more information on the original post. I have provided a link below. I hope that this information helps.


Make it a great day

Thank you :slight_smile: I hope this is going to be pushed in a future patch and not just the next big release.

Have a great day
