This was problematic in both PL and SL, but with all the portals in AL, the space bar has become a real problem. E.g., I was fighting near an exit in the Tower of Mardrom, and using the space bar to fire inadvertently popped up the exit dialog, interrupting me. This is a life or death situation, guys. Please do something about it.

Note: Similar things happen in other places—e.g. with Lisbet and Captain Rutger on the bridge—but none are quite so drastic as the Tower.
