Using Control Key in Multi-Line text fields causes Editor to hang

I am not sure if this is already reported but there is a bug (i guess) since Multi-Line comments/text fields exist.

Using ctrl to jump through multi-line text fields causes the complete editor to hang on me.

Steps to reproduce:

In 4.5, open static mesh editor and search for the source file path. This is a multi-line text field since engine version 4.5. Using the ctrl-key to jump around the words and then jumping back to the last character causes a crash.

This is also in previous versions for example when editing text in the “submit to source control” window. I did not test in any other multi-line text fields but I think 2 examples should be enough to make sure this is a problem in those multi-line comments/text fields and not in any other sub-system.

My system stats: Windows 7, UE 4.4.3 and 4.5.1

Thanks in Advance,

Guido

I’ve managed to reproduce this, and have located the bug.
I’ve created a pull request for the fix, which you can see here on Github.

Once Epic confirm, you should see this resolved in a coming release, or alternatively you can build from source and make the appropriate modification yourself.

Nice, thank you very much!

Hey guys, just letting you know that I’m working on this issue too. I was able to reproduce the freeze in 4.5.1 and I’m checking to see it’s fixed on our newest internal build. Thanks for reporting it!

Hi Jonathon, once you’ve either spotted an internal fix, or used my pull request, would you mind getting either yourself or one of the other techs to post a comment/accept/close the PR I have on Github for it? That way I get a notification and can close the branch with the fix/tidy up. Thanks.

Sure, I can do that. I’ll let you know.

Just a clarification for anyone watching this issue: twiddle’s pull request was accepted and integrated into main. The bug is now fixed.

Thanks, twiddle!
