Businessman Craig Whyte's proposed takeover of the Scottish champions is expected to be resolved in the next day or so after months of negotiations.
"I don't think so, I don't think there is any problem in that respect," he said.
"We have had those types of headlines for the last three years. For us, it's not a footballing issue.
"The problem that we have - which has happened to us on a few occasions at home this season - is that we have managed to get in front and teams have pegged us back all too easily in the games.
"That's a factor that has been an ongoing problem for us."
Asked if the loss to United was a major missed opportunity, Smith said: "They are all going to missed opportunities if you lose games.
"When you look at the championship overall, if you're saying that each of us with 10 games to play are going to win every game, we are not going to do that. I don't think anybody has had that level of run in the championship so far.
"We don't want to lose a game but if people consider we will win the next 10 games, we will be all right. But it won't happen like that, league championships never happen like that.
"We only look at today's game and say what we have to adjust to is the fact we have lost goals after getting in front on a number of occasions, instead of having the toughness to handle that situation."
