Maybe this is an overarching question as I’ve seen similar bugs in Firefox and I’d like to know how to avoid coding them.
For no apparent reason, the function keys, arrow keys (de-numlocked numpad as well), the 6 keys over the arrows, and backspace stop working. Every other key seems to work leading me to think it’s some sort of interrupt issue. It works again when I restart Delphi.
This is on an IBM Model M keyboard so certainly it couldn’t be a hardware issue, although if someone knows better I won’t be that naive, I’ve noticed this with different keyboards.
I’m not actually interested in a fix for Delphi, I just would like to know how to avoid keyboard input bugs. I’m most certainly debugging bug laden code. I just wonder why it causes parts of the keyboard to malfunction.
I doubt that it’s Delphi’s fault. I’m using Delphi 7 and never had this problem. I suggest you look for another culprit.
