I've got a problem with running after jumping: if i'm jumping while still pressing the running hotkey (Maj left), when i land i stop running, and i have to let the hotkey go to start running again.
It's really troublesome when I'm caught up in an intense battle, as i find myself walking toward enemies instead of running full speed with perks.
Oh I'm playing Blade btw so it makes the problem even worse...

Anyone as something similar? Bugs with running?

Edit: To clarify something:

Every time i jump and land with the hotkey for sprinting pressed, i stop sprinting when landing, and when i release the hotkey (for sprinting) i start sprinting again. It's like it inverse the hotkey until i press it again (my sprinting hotkey is on Hold Mod).
Some stuff like sidewalk or small items on the ground also stop the sprinting. Very inconvenient in most fights...

Yes - same here. Jumping stops the run so you can't run, jump, and keep running. It is annoying.
