whether commercial or freeware, it is always a gamble using a component -
inevitably there are issues that come up, some worse than others, that are in the realm of the component, and it can be scary to find yourself trying to debug a problem in the component and not being sure whose fault it is, nor understanding the code completely. especially if you don't have the source code.. sometimes its a win, sometimes a loss, it's hard to know ahead of time..
