I'm encounter an odd bug in SE21 and it's occurring more frequently in 22. This is in Ubuntu 14.04, SE 64 bit version. After editing code for several minutes, the keyboard buttons will suddenly stop working with their normal mappings after every 8-10 presses and start becoming the up arrow.
In the below image, I started on line 20. I continually pressed 1234567890 in order on my keyboard and no other keys. The result is that after a few presses, two 'UP arrow' commands are executed INSTEAD of the pressed number.
I would expect the image to have 12345678901234567890123... all on one line. But that's not happening and I have no idea why.
They keyboard works perfectly fine in every other open program. I'm typing this post with slickedit open and exhibiting the bug. No issues typing here or anywhere else.
I tried using the 'what is key?' menu option when this behavior is happening. The result says "Up runs the command cursor-up" So somehow the key input is being completely remapped into the Up key.
Closing and reopening slick edit resolves the problem for a bit before it reoccurs again.
Any ideas? I think the only keybinding change I made was to change ctrl-backspace to delete previous word.
