I was attempting to use the search feature on the request pipe and I am unable to type in the search field, I can how ever type in the number requested field. If I type in the Search bar I get no response if I use the letter keys, or the number keys on the number pad with NUM Lock on. If I press the Function keys or the non letter keys I get a Down arrow or some other such symbol. The only thing that seems to work right in the search feature is the backspace key will delete characters.

I am using version 4.4.3 Build #42
Forge: 10.12.2.1155-mc172

Fixed via 6618d8e

so how is that fixed ? i mean, how do i get the fix ? i have the same problem, using the same build. im sorry i don´t know what you mean with "Fixed via 6618d8e"

It means you need a version after 6618d8e. This is probably the latest, considering the date.

Update to version 4.4.4.43, the changelog states "FIX: Unusable text boxes in guis"
You won't magically receive fixes using the same build.
6618d8e is the commit (changes made to the code) that fixed the issue
