I have not been able to duplicate the issue, but I'm really hoping this (potential) fix solves the problem:

I think that, for wireless hosts, where it may take a little longer to connect, that the grid was still updating while it was trying to automatically resize the columns. The new version starts all the threads, one per remote host, prior to trying to automaticaly adjust the columns sizes so that all the data is visiable on the grid.
