VB and Windows Multitasking

Hi All,

I´m from Brazil, running a Portuguese windows, with english VB, and
i developed an application wich run´s background in windows screen, and work with the serial port, database (using SQL) and much more, but i´m having a big problem when i use my application with Internet Explorer and Word and another softwares together, i´m loosing some information from the serial port, i want to know if it´s a code problem of my application or no, and what i have to do?
I observed that when the computer it´s running some prossess, like saving, minimizing a window, closing a window, something happend with my software!

Thanks for all,
