Hackers taking over, How do I avoid this? Options

[Mirilion]

We just tried a Shadowrun one-timer, and it didn't go well. First, my friends like fantasy better, so that's that. However, one of them noted that the hacker, his player being very creative, simply took over everything and did everything. Not the fighting or the killing, but "table time" as it were. While the troll bounty hunter smashed things, the hacker had TONS of stuff to do out of combat while the others did very little.

We were playing by the basic rules of Food Fight, so the mage had less to do, but I guess it'll be the same for mages using the full rules. How do I avoid this?

The setting was a police station infested by a wendigo and his ghoul servants, with the power out. There was almost no matrix access to anything, and I can only imagine how bad it gets in normal runs.
