Hi beagah, that is one of many bugs that we've mechanically tuned as best we could within the 2 and a half month time limit to prevent from occurring.
Just curious, were you able to jump back off the door once this happened, or were you just stuck overall & the only other alternative was to close & re-open the window?
Overall, it's the game's way to push the character out of the computer's window despite there being a bunch of collisions in place to prevent this, therefore not allowing her to respawn in the starting spot once the in-game application starts back up.
The only solution we've conjured up so far is to simply walk through the door rather than jump in proximity of it, then progress from there.
